Savannah lost her pet monkey named Cleo. Savannah's friends, Ben and Griffin help finding Cleo. One day, their school went on a field trip and the field trip was a boat zoo. The zoo keeper is named Mr. Nastase. Their newest attraction, a monkey named "Eleanor" was actually Cleo! Now Savannah, Ben, and Griffin are on their mission to get Cleo back. I thought that Zoobreak was a really good book.
