Charleston, South Carolina.

Four years ago

Three girls disappear into the night. One by one they go missing, never to be seen again. No witnesses, no leads, nothing.

The only thing they had in common? An uneasy sense of being watched in the days before they vanished. Noises in the night, and boot prints in the flower beds outside their bedroom windows . . .

Today

One of the lost girls was Anna Klein's best friend. With no body, the case went cold. But Anna never stopped looking for Sylvie - or whoever took her.

Now, four years later, Anna finally has a lead when a body turns up in an abandoned mansion. She has to know: is it Sylvie? But time is running out. As the storm of the century threatens the whole East Coast, the clock is ticking to find the answers before this trail goes cold.

Can Anna find Sylvie and the other girls before they're lost forever?
