11 Birthdays

11 Birthdays by Mass, Wendy

I've read this book! I like it. On Leo and Amanda's tenth birthday, Amanda overhears Leo talking to some boys. They think havind your birthday party with a girl every year is sissy. Amanda runs home crying. They ignored each other for a year. Then, their 11th birthday begins repeating. They find out about a curse (or something like that) that was placed on their great grandfathers(maybe another great?). [Spoiler removed]
