But after their father unwittingly sends them to stay with an aunt who’s away on holiday, the Hardscrabble children take off on an adventure that begins in the seedy streets of London and ends in a peculiar sea village where legend has it a monstrous creature lives who is half boy and half animal. . . . In this wickedly dark, unusual, and compelling novel, Ellen Potter masterfully tells the tale of one deliciously strange family and a secret that changes everything.
