In this suspenseful, gripping novel, teen twin girls raised separately meet for the first time at their mother's funeral. Quinn has been trained to never tell a lie. Piper is a practiced liar. Narrated in both voices, the story of their quest to learn truths that have been concealed from them is shadowed by a dark spell that beckons them to run at night with a pack of murdering ghost hounds. Suspense, menace, mystery, witchcraft, family secrets, mistaken identity, and romance are interwoven in a brilliantly written page-turner that will grab and thrill teen readers.
