"Dr. Isla Cooper must travel to Port Lucy in Jamaica to locate the witch that placed a spell on her--one that puts her into a death-like sleep every night--before the spell becomes permanent"--Provided by publisher.

Doctor Isla Cooper is cursed: each night at midnight she falls into a death-like sleep and cannot be awakened for six hours. After a year, it becomes permanent. And the year is almost up. Desperate to find Malette, the witch who cursed her, Isla blackmails her way onto Daniel Pickett's private airship bound for the Caribbean, only to discover she's traveling with three illegal shapeshifters and Nigel Crowe, a government official determined to hunt down and exterminate every shapeshifter in England. -- adapted from back cover
