Love Curse — Steven E. Wedel

Keith's mother is dead, but that doesn't mean she's stopped trying to help him turn his life around. His dad, however, doesn't see any reason he or Keith should stop drinking or using drugs. Ashley and her two best friends have never known real love. When the girls make a road trip into a larger city near their home on the Oklahoma plains, they stumble upon a book in an estate sale that might be the answer to their romantic problems. When the school's renowned drug user approaches Ashley, she doesn't think there's any way she'd ever fall for Keith. As her friends use the grimoire to wreak havoc on the boys of the school who have mistreated them, Ashley can't help but wonder if Keith's interest is real or the result of the spells her friends claim to be creating. Then the high school erupts in chaos and the unlikely couple have to work against the evil that has been unleashed on their small town.
