Prophecy of the Sisters (Prophecy of the Sisters, 1)

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, they find themselves entangled in a mystery that involves a tattoo-like mark, their parents' deaths, a boy, a book, and a lifetime of secrets.
