When 19-year-old Meg Briggs wakes up after having a crazy party with her friends, she finds a girl in the pool.

Dead.

Who is this girl?

How did she end up in the pool?

Was she even at the party?

Even more strange is when they pull her out of the water, Meg realizes the girl looks very familiar. As a matter of fact, she looks just like her.

Like an identical twin.

But Meg has no twin, at least none that she knows of, and no one at the party knows this girl or can say where she is from.

What is Meg’s mom hiding from her?

FBI profiler Eva Rae Thomas is caught in distress at home with her children and between the two men in her life when she is asked to help out on the case.

Who killed Meg’s identical twin and why? And where did she come from?

As Eva Rae Thomas digs deeper into the story, she can barely believe the revealed secrets, secrets so cruel that someone is ready to go to great lengths to keep them hidden.
