📖 About This Bibliography
John Patrick Green is an American author, illustrator and cartoonist best known for creating the bestselling children’s graphic novel series InvestiGators.
His work combines visual comedy, imaginative characters, fast-paced adventures and an unmistakable fondness for puns. Many of his stories feature animals navigating surprisingly human situations, from investigating crimes to building houses and finding employment.
Although InvestiGators brought him international recognition, Green’s career in comics began long before the publication of its first volume in 2020.
He has worked as an illustrator, co-creator and writer on projects including Jax Epoch and the Quicken Forbidden, Teen Boat!, Hippopotamister and Kitten Construction Company.
His bibliography also includes collaborations with other comics creators, particularly Christopher Hastings, Dave Roman, Pat Lewis and Steve Behling.
This BookFairy bibliography brings together his original graphic novels, comics, spin-offs, supplementary publications and collected editions, organised by publication date and recommended reading order.
It also distinguishes works written and illustrated by Green from projects on which he collaborated with other creators.

🐊 InvestiGators — Complete Reading Order
The InvestiGators series follows Mango and Brash, two alligator secret agents working for S.U.I.T. — Special Undercover Investigation Teams.
Their missions combine detective mysteries, technological gadgets, absurd villains, slapstick humour and elaborate visual jokes.
Created for middle-grade readers, the books are also entertaining for adults who appreciate clever wordplay and inventive graphic storytelling.
📚 Publication Order (Recommended)
- InvestiGators (2020)
- Take the Plunge (2020)
- Off the Hook (2021)
- Ants in Our P.A.N.T.S. (2021)
- Braver and Boulder (2022)
- Heist and Seek (2022)
- All Tide Up (2023)
- Class Action (2024)
- Case Files (2025)
- Weather or Not (2026)
Recommended reading order: Publication order.
Although individual adventures are relatively accessible, reading the series from the beginning provides the best introduction to its recurring characters, relationships and running jokes.
About the Series
The first novel introduces Mango and Brash as investigators equipped with advanced spy technology and a highly unconventional approach to travelling between locations.
As the series continues, their investigations become increasingly elaborate, introducing unusual adversaries, surprising inventions and recurring characters.
The artwork plays a central role in the storytelling. Facial expressions, background details, visual jokes and page layouts frequently carry as much humour as the dialogue.
🕵️ InvestiGators: Agents of S.U.I.T.
Agents of S.U.I.T. is a spin-off that expands the original universe by focusing on other members of the organisation.
The books feature collaborations between Green and other creators.
Complete Published Reading Order
- Agents of S.U.I.T. (2023)
- From Badger to Worse (2024)
- Wild Ghost Chase (2025)
- Sew Much Trouble (2026)
Forthcoming
- Tomb and Gloom (2027)
Creative Collaborations
The first four volumes involve:
- John Patrick Green — co-creator and writer
- Christopher Hastings — co-writer
- Pat Lewis — illustrator
The fifth volume, Tomb and Gloom, is credited to John Patrick Green and Zac Gorman, with illustrations by Pat Lewis.
Recommended Reading Order
Readers can begin with Agents of S.U.I.T. independently, but familiarity with the main InvestiGators series adds context to the organisation, its technology and recurring characters.
For a comprehensive reading experience, I recommend starting with InvestiGators before moving to the spin-off.
🐱 Kitten Construction Company — Complete Bibliography
Kitten Construction Company is a humorous children’s graphic novel series about a group of kittens whose professional ambitions are repeatedly underestimated because of their adorable appearance.
The books explore teamwork, determination, creativity and the importance of recognising people’s abilities rather than judging them by appearances.
Complete Reading Order

- A Bridge Too Fur (2019)
Both volumes were written and illustrated by John Patrick Green.
Series status: Complete duology.
🚤 Teen Boat! — Complete Collected Editions
Before InvestiGators, Green collaborated with writer Dave Roman on Teen Boat!, a humorous comic series built around an unusual superhero concept.
Its central character is a teenager who can transform into a boat, creating endless opportunities for jokes about adolescence, friendship and fitting in.
Collected Graphic Novels
- Teen Boat! (2012)
- Teen Boat! The Race for Boatlantis (2015)
Creative team:
- Dave Roman — writer and co-creator
- John Patrick Green — illustrator and co-creator
The collected books developed from earlier comics material.

Jax Epoch and the Quicken Forbidden is one of Green’s earlier comics projects, created with Dave Roman.
The series predates his better-known children’s graphic novels and was originally published in serialised comics form.
Collected Volumes
- Borrowed Magic (2003)
- Separation Anxiety (2004)
Creative team:
- Dave Roman — writer and co-creator
- John Patrick Green — illustrator and co-creator
The 2003 and 2004 dates refer to the collected editions, not the original appearance of the serialised material.
🦛 Standalone Graphic Novels
Hippopotamister (2016)
Hippopotamister is a standalone children’s graphic novel written and illustrated by John Patrick Green.
It follows a hippopotamus who leaves his deteriorating zoo in search of employment and a more satisfying life in the human world.
The story combines animal humour with questions about identity, work, perseverance and discovering where someone truly belongs.
Unlike Green’s continuing series, Hippopotamister can be read as a complete, independent story.
📗 Shorter Works, Specials & Companion Books
Beyond the numbered InvestiGators volumes, Green has contributed to additional publications expanding the series’ world.
InvestiGators: High-Rise Hijinks (2024)
Published for World Book Day 2024, this short graphic novel features Mango and Brash investigating a mysterious crime involving a missing building.
The publication credits John Patrick Green and Christopher Hastings, with illustrations by Pat Lewis.
It is a supplementary adventure rather than a numbered instalment of the main series.
InvestiGators: The Big Snappy Joke Book (2026)
Published in September 2026, this companion book collects jokes, puns and illustrated humour featuring characters from the InvestiGators universe.
It is intended as a humour book rather than a conventional detective story.
InvestiGators: Puzzle Adventures (2027)
An announced activity book featuring puzzles and interactive challenges inspired by the InvestiGators universe.
As of October 2026, this publication remains forthcoming.
📦 Omnibus, Boxed Sets & Other Editions
The success of InvestiGators has led to several collected packages and alternative formats.
These include:
- InvestiGators boxed sets
- InvestiGators: Inspection Collection
- InvestiGators: Agents of S.U.I.T. boxed sets
- InvestiGators Audio Collection: Books 1 & 2
- Paperback reprints of originally published hardcovers
- Digital editions of previously published graphic novels
These publications repackage existing material and are therefore not counted as new stories in the principal bibliography.
Audiobook adaptations are also treated as alternative formats rather than original literary works.
🇷🇴 Romanian Translations
As of October 2026, no officially published Romanian-language translations of John Patrick Green’s books have been confirmed.
This includes:
- InvestiGators
- Agents of S.U.I.T.
- Kitten Construction Company
- Hippopotamister
- Teen Boat!
- Jax Epoch and the Quicken Forbidden
Romanian bookstores may stock these publications in English, but availability through a Romanian retailer does not mean that a Romanian translation exists.
For this reason, the bibliography retains the original English titles.
This section will be updated if an officially licensed Romanian edition is announced.
💜 Books Reviewed on BookFairy
My introduction to John Patrick Green came through InvestiGators: Weather or Not.
Although it was a later volume in the series, I found it surprisingly accessible and thoroughly entertaining.
I particularly enjoyed the energetic illustrations, absurd humour and clever wordplay. The story was easy to follow, the characters were immediately likeable, and the visual jokes frequently made me smile.
While I would have welcomed a slightly more surprising mystery, the book delivered an enjoyable reading experience.
