Priscilla Rat is excited about going to her best friend Rosy’s house to work on a new puzzle, at least until she receives a better offer and is tempted to lie to get out of her commitment. Priscilla tries on a list of lies, from illness to forgotten appointments, before her eyes rest on a picture of the two of them smiling together. Remembering how Rosy saved her life in a horrible storm, Priscilla realizes that some things are more important than taking a ride on a boat. Priscilla wakes the next day to go visit Rosy only to find that she is sick and after trying to find something else to do decides to take her sick friend dinner in bed and a favorite book. Wonderful illustrations of the rats’ world are reminiscent of the lives of the Borrowers. A teacup with button wheels serves as a baby stroller, safety pins become useful fishhooks, and a spool makes a wonderful night stand. This tale of friendship is charming even if it is a bit predictable. Luckily, the amusing illustrations carry the plot over the rough patches. More Priscilla Rat adventures are sure to be eagerly anticipated. (Picture book. 4-7)
