As the Charmed Ones know, it's difficult to adjust to the ideas of having powers and saving innocents -- that's one of the reasons that their Grams bound their powers until the sisters were ready to receive them. In fact, many witch clans keep the powers of their young dormant until the recipient of the power reaches a certain age. In Juliana O'Farrell's clan, that age is thirteen -- the exact age of her daughter, Lily. By the day after her thirteenth birthday, though, Lily's powers haven't manifested, and Juliana's worried that a demon may have stripped her daughter's magic. Enter the Halliwell sisters. But Lily's too much of a typical teen to welcome witch chaperones. She'd much rather sneak out to hang with her rebellious friend, Drew. Could Drew's bad behavior be related to Lily's missing magic? It's going to take the Power of Three to get to the bottom of this adolescent angst!
