Gwen Vaughan is an Old One with a mission: search out all seven signs and combine them into a powerful new sigil to strengthen the Light. She's found three, but can she discover the hiding places of the remaining four before her lethal enemy, the evil enchantress Lilith, can destroy her… and everyone she loves?

Gwen's allies, human and Old One alike, are determined to help her succeed, but the Queen of Darkness is equally determined to make Gwen's 23rd birthday her last. With the violence escalating, will Gwen find the strength to finish her quest?
