Runaround — Helen Hemphill

In this Booklist Top Ten Romance Book, everything eleven-year-old Sassy knows about love comes from the magazine Love Confessions. But now that she has her eyes on her handsome neighbor, Boon, she wants more details. Only nobody will talk to her, not her widowed father or her never-married housekeeper or, worst of all, her gorgeous sister, Lula, who has more boyfriends than she can shake a stick at. When Lula sets up Sassy for an embarrassing moment, Sassy vows revenge: she will make Boon her boyfriend and show Lula a thing or two in the process.
