Cyclone of Truth

Marge is sixteen, but she already knows love, heartbreak, and death in the family. Unhappy and lonely she buys a paperback "Witchcraft for Idiots - A Complete Guide for the Modern Day Wicca Practitioner" and starts performing rituals. She doesn't expect them to work. In her own words, "it's all mambo-jumbo, new age stuff, self-motivational crap."
After several careless choices, her life starts to unravel and her family's deepest secrets start to come out. Those secrets are both recent and ancient, mundane and the ones that connect her to the American Revolution, Arthurian legends, Roman Empire, foundations of Christianity, Atlantis, and even involve something large, furry, and intelligent. Marge has to sort out friends from enemies, discover who she is and what she can do, and just plainly survive as supernatural forces stalk her and her friends across two continents.
