NEW YORK TIMES BESTSELLING SERIES * When there are suspicious sightings around the bay (ghosts?! a sea monster?!)-who're you gonna call? An elite team of crime-fighting underdogs, that's who! The Misfits are on the case in the hilarious series from Newbery Honoree Lisa Yee and Caldecott Medalist Dan Santat!
"For any kid who's felt like a misfit, this crackling adventure packs a wallop!" -Lincoln Peirce, creator of Big Nate
Oof! When reports of ghosts arise around an abandoned lighthouse, Olive and her elite team of underdogs are immediately thrust into a brand new case. After all, ghosts don't exist . . . right?
Real or not, the ghosts draw quite a crowd at Olive's beloved Reforming Arts School, or RASCH (not "rash"). Turns out everyone wants a glimpse of the ghosts, including . . . the nearby marine life?!
Between RASCH's ghosts and newfound tourism, rumors soon spiral out of control about a sea monster in the bay-snagging unwanted attention from a corrupt mogul. What is going on at RASCH? Does the mythical creature really exist, and can the Misfits save it from being captured? The team will have to dive deep to get to the bottom of San Francisco's most legendary mystery. . . .
For other Misfit adventures, don't miss The Misfits #1: A Royal Conundrum and The Misfits #2: A Copycat Conundrum!
