Ten-year-old Celie’s grandmother has moved in with her family, and Granny’s forgetfulness is starting to worry Celie. In the meantime, she can tell her parents are keeping secrets, but she can’t talk to her best friend Lula or her sister Jo, because they’re both keeping secrets, too! Why is Lula not sharing with Celie? Who is Jo texting all the time? And what is Celie supposed to do when special time with her grandmother becomes much more complicated—and possibly dangerous—than Celie can manage on her own? Once again Celie turns to her diary as she tries to sort this all out, filling the pages with heartfelt and often humorous entries, notes, drawings, and pages from her top-secret spy notebook.
