11 Birthdays by Wendy Mass

Hi everybody.  I just finished this one and it's not too bad.  Kind of like Groundhog Day for kids.  Leo and Amanda are reliving their 11th birthday, over and over again, and they don't know why until they talk to a mysterious little white-haired lady.  Find out if they ever live to see another Saturday in this 2011-2012 Mark Twain Nominee.  It's a quick read and a pretty good story.
