Effie is one of the few humans living on an island full of mutants. After a prank goes horribly wrong, they work off their debt by looking after children with powers. And then they get a job taking care of the most famous children in all of Mutopia. Now they're missing, and Effie has to help find then. It'll be a dangerous journey facing wolves, evil mutants, imprisonment, and nightmares.

Not to mention the scariest part of all - talking to their crush.

Effie has no powers. Can they really save the day?

"Full of action, fast-paced adventure, lovable characters, and queer joy, THE MUTANTSITTERS CLUB is an absolute delight of a read."

Christina Li, author of CLUES TO THE UNIVERSE

"Set in a post-war society where utopic ideals are juxtaposed with echoes of bigotry, The Mutantsitters Club captures the same diversity and punk energy as Whitby's original YA series, combined with a softer voice and hilarious middle grade hijinx. With complex worldbuilding and energetic plot, Whitby trailblazes themes of community, bravery, and identity through the eyes of a non-mutant nonbinary main character living in a world of supernaturally gifted peers. The young mutants in your life will enjoy this heartfelt romp!"

Ash van Otterloo, author of CATTYWAMPUS and A TOUCH OF RUCKUS
