Lissa Dragomir is a Moroi princess: a mortal vampire with a rare gift for harnessing the earth's magic. She must be protected at all times from Strigoi; the fiercest vampires--the ones who never die. The powerful blend of human and vampire blood that flows through Rose Hathaway, Lissa's best friend, makes her a Dhampir. Rose is dedicated to a dangerous life of protecting Lissa from Strigoi, who are hell-bent on making Lissa one of them. After two years of freedom, Rose and Lissa are caught and dragged back to St. Vladimir’s Academy, where vampire royalty and their guardians-to-be prepare for a life fraught with danger. Rose and Lissa must navigate their treacherous world and never once let their guard down, lest the evil undead make Lissa one of them forever. But soon Rose finds herself gripped by temptation of forbidden love, leaving Lissa exposed to Strigoi attack.... Now she must choose between the best friend she lives for, and the man she can't live without.
