All the Colours of the Dark by Chris Whittaker

Late one summer, the town of Monta Clare is shattered by the abduction of teenager Joseph 'Patch' Macauley. Nobody more so than Saint Brown, who will risk everything to find her best friend.

But when she does: it will break her heart.

Patch lies alone in a pitch-black room - until he feels a hand in his. Her name is Grace and, though they cannot see each other, she lights their world with her words.

But when he escapes: there is no sign she ever even existed.

Left with only her voice and her name, he paints her from broken memories - and charts an epic search to find her.

As years turn to decades, and hope becomes obsession, Saint will shadow his journey - on a darker path to hunt down the man who took them - and set free the only boy she ever loved.

Even if finding the truth means losing each other forever...
