Lulu's Mysterious Mission by Judith Viorst

4.0

In this third book about the extraordinarily difficult Lulu, her parents are taken a grown up only vacation and leaving Lulu in the care of Sonia Sofia Solinsky, the best babysitter in maybe the world. Lulu, as you might expect, is not going quietly along with this plan. After doing everything in her power to get rid of Ms. Solinsky, Lulu finds out something remarkable. Her babysitter is actually a former spy trainer (codename Triple S)! Well now, that changes everything. Suddenly Lulu finds that she wants to be a spy more than anything. But can she live up to Triple S's remarkably high standards? A fun read, recommended for grades 2-4.
