Nightmare Island by Shakirah Bourne

From rising star Shakirah Bourne, author of Josephine Against the Sea, comes a mysterious adventure that explores one of the most chilling tales in Caribbean mythology: the faceless douen children.

Twelve year-old Serenity Noah has never told anyone about her recurring nightmares -- the haunting images of silver butterflies whose flapping wings drive away all sound, leaving only suffocating silence in their wake. Her parents already favor her "perfect" younger brother, Peace, and she doesn't want to be seen as the "problem" child.

Instead, Serenity's found a productive way to channel her fears: creating a horror movie as scary as her nightmares.

When Peace suddenly becomes afraid of the dark and refuses to sleep alone, their parents take him away for "treatment" on Duppy Island. Serenity has a very bad feeling about the mysterious island and the facility's creepy leader, Dr. Whisper. And when she sees a silver butterfly from her nightmares in the forbidden forest she realizes that something is seriously, dangerously awry.

But nothing could've prepared Serenity for the truth: the island is home to douens -- faceless children with backward feet who are trapped in limbo between the world of the living and the land of the dead. And unless Serenity acts soon, her brother is going to join their ranks...
