A Xavier’s Institute Novel

By Jaleigh Johnson

X-Men super-soldier Fantomex faces off with clone versions of himself in this thrilling Super Hero heist adventure from Marvel’s Xavier’s Institute

Former super-soldier and master thief, Fantomex, stumbles upon one of his clones, Cluster, breaking into museums to steal priceless artifacts. Outwitted and intrigued, Fantomex decides to beat Cluster at whatever game she’s playing. But something is different about these artifacts: they’ve all been infused with nanotechnology, very similar to the kind that originally created Fantomex. And they aren’t the only ones looking for them… Their other clone, Weapon XIII, is on the hunt too. The cat-and-mouse heists test their burglary skills and push the boundaries of how much they can trust one another. When it turns out that they’re the pawns in an even deadlier game, all hell breaks loose – and these clones always play to win.



It isn’t easy being extraordinary. Superhuman powers can be both a gift and a curse in a world where those talents can be used for good or evil. A lucky few are taught how to control their abilities at the Charles Xavier Institute, while others must master their uniquely dangerous powers alone. Will they become true heroes and heroines when called upon to defend the world, or turn their fearsome abilities to conquering the world? Meanwhile, in a realm beyond Earth, mighty heroes do battle with monsters of myth and undertake quests to restore peace and honor to the legendary halls of Asgard and the Ten Realms.

Interviews and Articles

Triptych went well above my expectations. Fast paced action, heartfelt moments, funny moments, fabulous writing style, brilliant characters and characterizations and a snarky protagonist what isn’t to love?”
What You Tolkien About

“So its great to see how the author has really delved into the self-doubt and questioning that plagues us all in those times, but she shows that for Fantomex, and for most of us, there is a light at the end of the tunnel and you can get there, so in that respect, the book is quite hopeful in its theme.”
– Big Geordie Geek

“I gave Triptych five stars. It had everything I have come to expect from this series of Marvel prose novels from Aconyte books.”

– Chris L. Owens

“What makes this book work so well for me is that it is as much about the plot as it is about character development. Both Avery and Fantomex grow a lot throughout this story, and have to learn that it is okay to trust/depend on other people… even though you have been hurt and disappointed in the past. You don’t have to be alone and push people away… which is definitely something that hit close to home.”

– Simply a Book Drunkard

” This is something else, this is something a little special. It shows a human side to these characters, a vulnerability and complexity that is often left out of comics to make more room for explosions and fist fights. If you’re after something a bit different, something that isn’t just the standard comic book formula this is a book you’re definitely going to want to read.”

– Trans-Scribe

“The themes of self, identity and finding one’s place resonate in the story, making it a quick and exciting read. Recommended for Marvel fans, super-hero fans, and just general action fans.”
Martin’s View

“An engaging world rich in detail, mayhem, and adventure.”
– Kirkus Reviews

 “Johnson’s immersive world building is vivid… [with] fast-paced action, compelling characters.”
– Booklist
