When Ari and Kaylan decide to make a list of 11 things they MUST do before they turn 12, they have no idea they’re starting an ongoing tradition. But what begins as a fun project ends up changing their friendship, their school, and their neighborhood—for the better.

This is the complete series - with all four books - especially signed by acclaimed Author Lisa Greenwald. 

"11 before 12";  "12 before 13"; "13 and Counting", and  "13 and 3/4".   

This is a perfect summer read!!!!
