Growing up in the same motorcycle club, Arthur Killian and Cleo Price were as close as siblings until the night he set her home on fire. Her testimony sent him to prison, but he used his talent with numbers to secure an early release. When Arthur and Cleo's paths cross again, he knows he's found the perfect opportunity for revenge.

The sole survivor of the fire that killed her parents, Cleo grew up with painful scars covering the entire right side of her body. Now, though, she wakes up with tattoos covering the left half, and no memory of how she got them. In fact, she remembers nothing from her previous life. The only thing she knows is that her captor is familiar, and he makes her feel things she never thought possible. But he has secrets about her past, and Cleo discovers that the truth may be hidden in the markings covering her body.
