The Nest by Kenneth Oppel
In this beautiful, menacing novel, perfect for fans of Neil Gaiman's Coraline, an anxious boy becomes convinced that angels will save his sick baby brother. But these are creatures of a very different kind, and their plan for the baby has a twist. Layer by layer, he unravels the truth about his new friends as the time remaining to save his brother ticks down.
With evocative and disquieting illustrations by Caldecott Medal and Governor General's Awardwinning artist Jon Klassen, The Nest is an unforgettable journey into one boy's deepest insecurities and darkest fears.
