As far as 11-year-old Aggie knows, everything is great. Friends, school, family all are fine--and fun and predictable. But one random day, Aggie's longtime friend Fiona starts to pull away, canceling plans and acting, well, kind of different. It's not like anything happened--or did it? There aren't any good answers, and Aggie is left wondering how she's supposed to act now that her friend seems to have moved on without her. As Aggie finds her way through this difficult (and sometimes painful) loss of friendship, can she open her heart up to a new friend?
