Fang-favorite characters Spelldon Cauldronello and Kieran Valentine are starring in a multiverse adventure that includes glimpses into monstrous steampunk, pirate, and Wild West worlds, featuring alternate versions of popular Monster High characters.

Spelldon is eek-vited to a once-in-an-unlifetime summer internship with the all-powerful guardian of the Boomuda Triangle, the place where all worlds are kept in balance. His boofriend, Valentine, is defrighted for him, but he can’t help worrying about what the weeks apart will do to their relationship. What if Spelldon forgets him? What if the guardian is scary hot?! What if he falls into a wormhole?!?! 

So Valentine secretly follows Spelldon to the Boomuda Triangle to make sure no shenanigans happen and accidentally kind of unintentionally causes all the universes to rip apart and converge…oops! Spelldon and Valentine will have to overcome their insecurities, mend the rips, and find each other in every universe. Easy queasy!
Megan Brown is an editor at Oni Press who has worked on titles like Marvel Action: Captain Marvel, Read Only Memories, GLOW, Dungeons & Dragons, TMNT, Star Trek, My Little Pony, Napoleon Dynamite, Godzilla, and more.

Eileen Widjaja is a comic and cover artist who has worked with IDW Publishing, Bad Egg Publishing, Dauntless Stories, and more. They are known for their work on Monster High and their chameleon-like ability to adapt their style to fit the unique tone of every project. When not on their drawing tablet, they’re probably café-hopping or nose deep in a historical novel.
