A lifetime missing. Just three weeks to find her. The brand new thriller from the New York Times no. 1 bestselling author.

Frankie never thought she'd be hired by a serial killer.

Especially not the notorious Beautiful Butcher, who is awaiting execution in just three weeks' time and whose dying wish is to find her missing younger sister, Lani.

And so it is that Frankie finds herself working undercover on an isolated island off the coast of Hawaii, to see if Lani is being held captive by the Beautiful Butcher's ex-boyfriend.

But whose word can she really trust? And what do her new co-workers know?

As a tropical storm rolls in, cutting Frankie off from the outside world, she can't help but wonder...

Is this her most dangerous case yet?
