As the world's only mutant detective agency- X-Factor Investigations welcomes all cases - the stranger- the better! And their latest gigs involve gods- vampires- the disappearance of the Invisible Woman and the ever-volatile state of mutant politics - lurching from a literal Utopia to a damaging Schism! But in the wake of a heartbreaking loss- the team has splintered - and Jamie Madrox begins a quest for the answers he needs to feel whole again. What does his future have in store? Meanwhile- Siryn faces the fight of her life- and a traumatized Wolfsbane returns with a baby on the way - only to learn that her ex-boyfriend- Rictor- has a new love! And will a member of X-Factor fall? It's an X-book like no other!
