Where the Shadows End by Louisa Bello

Sam, a 45-year-old Londoner of dual heritage, has lived his life accompanied by voices no one else can hear. When his elusive, dream-like girlfriend disappears without warning, Sam's fragile world begins to unravel.
As the past and present collide in Sam's fractured mind, he is drawn into a labyrinth of memory and revelation that challenges everything he thought he knew. But the voices that haunt him may yet become his guides, if he can only find the courage to listen.
Where the Shadows End is a powerful meditation on self-acceptance, the nature of guilt and the need to belong.
