is the first book in Leslie Calderoni's Tempest Trinity, a smart new Young Adult trilogy packed with mystery, girl power, and the magic of science. "I'm really excited to get onto the shelves...With its themes of Girl Power and family bonds, it's a fun book for a wide age range." Few forces are stronger than the bond of sisterhood. The laws of physics are a close second, though--at least for Emerald, Mia, and Terra, three teenagers whose talents allow them to control time, talk to people no longer living, and manipulate the string vibrations that make up the universe. Even with these "charms," the girls have their work cut out for them when faced with an elaborate thread of mysteries: What family secret is Mama and Auntie Eva trying to hide from them? What is Colin, the menacing boy from New Orleans, so desperately looking for here in Santa Cruz? Matters are further complicated when Emerald is blindsided by an instant and highly impractical attraction to a new boy in town. Together, the Tempest sisters must unravel these mysteries before family tensions boil over, all the while still learning the nature and extent of their powers.
