Nikki Kill doesn't see the world in black and white. Her synesthesia colors everything in view, transforming objects and numbers into emotions and clues. This means she's a dangerous commodity to anyone with something to hide.

Nikki has already taken down the Hollises--one of LA's most powerful families--for murdering her half-sister Peyton. Now she's training to join the ranks of the police academy. Before she knows it, Nikki is on the trail of a cold case that couldn't be any more personal-the death of her mother.

But when the web of lies and secrets she uncovers leads back to the people who have tried to silence her, Nikki must pursue the blue tint of justice or everything--including her life--will be lost.
