Twenty million in diamonds missing.

Kate Sawyer, a cop in witness protection, holds the key.

If she could only remember.

Early-onset Alzheimer’s clouds the past. Stem cell therapy is working to clear it.

But time is running out for Kate.

One night she finds a dead man in her bathtub with a note stuck in his pocket.

I know what you’ve done.

Her cover blown, Kate runs, the clock is ticking. People close to her are being killed.

Shadowy memories tease her. Some she recognizes. Others don’t seem familiar at all.

Running from people she can’t remember, dogged by a past lost in the haze, Kate discovers no one is who they appear to be, perhaps not even herself.
