ELLIE spent the summer before seventh grade getting dropped by her best friend since forever. JACK spent it training in "The Cage" with his tough-as-nails brothers and hard-to-please dad. By the time middle school starts, they're both ready for a change. And just as Jack's thinking girls have it so easy, Ellie's wishing she could be anyone but herself.
Then, BAM! They swap lives - and bodies!
Now Jack's fending off mean girls at sleepover parties, while Ellie's reigning as The Prince of Thatcher Middle School.
As their crazy weekend races on - and their feeling for each other grow - Elli and Jack begin to wonder if maybe the best way to learn how to be yourself is to spend a little time being somebody else.
