Megan and Noah live near the Clarksville City Zoo. One night, Megan is looking around with her binoculars when she notices monkeys running around like crazy at night. She tries to point it out to her brother, Noah, but he dismisses her observations. Determined that something is going on, Megan begins taking as many notes as she can about the zoo.
It's not too long after that night that Megan has disappeared. When the official search turns up nothing about her potential whereabouts, Noah begins to suspect that the zoo is somehow connected to Megan's disappearance. She becomes even more convinced of this when he is visited by a bird, who delivers a message for him to visit Mr. Tall Tail at the zoo.
That visit opens up enough questions that Noah gets his friends, all members of The Action Scouts, involved in the investigation and search. However, not everyone at the zoo seems to want to help, and some are outright hostile to the kids. Will Noah and his friends be able to find Megan? And just what is going on with all the animals?
This was such a fun story. The characters were fairly well-written for a middle-grades book, and the mystery the kids begin to uncover was really neat. I don't want to give away too much about what is actually happening at the zoo, but I will say that I really loved how involved the animals were in helping Noah and the Action Scouts find Megan.
For this book, I listened to the audiobook. The narrator, Patrick Lawlor, did a wonderful job with the book. His narration really pulled me into the story and, though I was intending to just listen to it a little bit at a time and spread the book out over a few days, found that I could not do that. It was so good that I had to keep listening, to the point that I had listened to the entire story before I had even realized it.
So, if you like middle grades stories with mystery, and mischief - both of the human and animal variety - then this is probably a story you will enjoy.
