"Seraphina Ramon will stop at nothing to find out the truth about why her sister Eff is in a coma after a very suspicious 'accident.' Even if it means infiltrating the last place Seraphina knows Eff was alive: a once-abandoned amusement park now populated by a community of cultists--the Merry Dredgers. Follow Seraphina through the mouth of the Goblin: To the right, a wolf-themed roller coaster rests on the blackened earth, curled up like a dead snake. To the left, an animatronic Humpty Dumpty falls off a concrete castle and shatters on the ground, only to reform itself moments later. Up ahead, cultists giggle as they meditate in a hall of mirrors. This is the last place in the world Seraphina wants to be, but the best way to investigate this bizarre cult, is to join them." --Publisher marketing.
