Thirteen-year-old Evan Brown has made a confused statement about a 'blackness' coming out of the ceiling and attacking his parents. His mother is in a coma; his father, missing since the attack, is the prime suspect. The police assume it's a case of domestic violence and that Evan is traumatised. Evan certainly doesn't want to make things worse by revealing he can hear a voice inside his head - Kenji - a voice he's never wanted.
When dark shadows appear in the tree outside his window and a mysterious cat begins to stalk him, Evan starts to believe he really must be losing his mind, but with no new leads and the police becoming increasingly suspicious, he is left with no choice but to follow Kenji across a bridge into an unknown and dangerous challenge. Can he undo the damage that's been done and save others, not just himself, from harm?
Family secrets and cosmic forces are at work in this gripping story for young adult readers.
