Shattered Mirror (Den of Shadows)
It's not easy being a vampire-hunting witch, but Sarah Tigress Vida has  learned from the best. The witches of the Vida family line have been  successfully stalking and staking the undead for centuries, and Sarah is  immensely proud of her ancestry. So, the last thing she would ever do is  befriend one of the enemy. She has always faithfully followed the golden Vida  rule of vampire hunting: "Knowing your prey can cause hesitation, and when one  is a vampire hunter, hesitation ends in death." Then she meets artistic, sweet  Christopher. A benign vampire, Christopher lives off of animal blood or the  blood of willing human donors, and begins to gently woo Sarah with his poetry  and drawings. Completely against her slayer instincts, Sarah reluctantly begins  to care for Christopher... until she discovers that his twin is the vampire  Nikolas, infamous for his habit of carving his name into the flesh of his  victims. Sarah has always sworn to be the Vida to take Nikolas out, but her  feelings for Christopher have allowed her to hesitate--a hesitation that may  cost her not only her family's sterling reputation, but her mortal soul.WithShattered Mirror, wildly popular teen author Amelia Atwater-Rhodes  continues to effectively tap the vein of universal adolescent fascination with  all things brooding and blood-sucking. Ardent fans will be pleased to see the  return of characters from the author's previous books, like healer witch Caryn  Smoke. This complex dynasty of witches and vampires will no doubt enjoy long,  imaginary lives as the young author continues to hone her witch... er, writing  craft. (Ages 12 and older)--Jennifer Hubert
