Bestselling author Carolyn Jess-Cooke has written a brilliant novel of suspense that delves into the recesses of the human mind and soul--perfect for fans of Gillian Flynn and Lisa Unger. ''The Boy Who Could See Demons'' follows a child psychologist who comes up against a career-defining case--one that threatens to unravel her own painful past and jeopardizes the life of a boy who can see the impossible. Dr. Anya Molokova, a child psychiatrist, is called in to work at MacNeice House, an adolescent mental health treatment center. There she is told to observe and assess Alex Connolly, a keenly intelligent, sensitive ten-year-old coping with his mother's latest suicide attempt. Alex is in need of serious counseling: He has been harming himself and others, often during blackouts. At the root of his destructive behavior, Alex claims, is his imaginary ''friend'' Ruen, a cunning demon who urges Alex to bend to his often violent will. But Anya has seen this kind of behavior before--with her own daughter, Poppy, who suffered from early-onset schizophrenia. Determined to help Alex out of his darkness, Anya begins to treat the child. But soon strange and alarming coincidences compel Anya to wonder: Is Alex's condition a cruel trick of the mind? Or is Ruen not so make-believe after all? The reality, it turns out, is more terrifying than anything she has ever encountered. A rich and deeply moving page-turner, ''The Boy Who Could See Demons'' sets out to challenge the imagination and capture the way life takes unexpected turns. In the best storytelling tradition, it leaves the reader changed.
