An ancient prophecy divides two sisters

One good... One evil...

Who will prevail?

Twin sisters Lia and Alice Milthorpe have just become orphans. They have also become enemies. As they discover their roles in a prophecy that has turned generations of sisters against each other, the girls find themselves entangled in a mystery that involves a tattoo-like mark, their parents' deaths, a boy, a book, and a lifetime of secrets.

Lia and Alice don't know whom they can trust.

They just know they can't trust each other.
