Practically MagicPractically Magic

"The Hadley sisters of Mystic Hollow are magic. Literally. But for all the generations of witches behind her, Kat Hadley could swear that she's utterly invisible to boys. Then she learns that her perfect older sister, Harriet, cast a curse to protect her from heartbreak. Kat is so furious, she loses control--and it's not just their sisterhood that shatters. It's magic itself. Suddenly, every spell a Hadley witch has ever cast starts reversing. Spells to do good start bringing evil. Curses to repel suddenly attract. And the veil between worlds begins to thin. If Kat and Harriet don't do something fast, this Halloween might be Mystic Hollow's last. As they race to repair the balance of magic--and their relationship--Kat notices that every crush who's ever rejected her is suddenly magically lovesick. Even her annoying class rival seems to have fallen under her spell. For the first time in her life, she feels practically magic. Who cares if it's all just a spell?"--
