The Book of Secrets — Cynthia Voigt

From Newbery Medalist Cynthia Voigt, Book II in the exciting adventures of Mister Max -- 12-year-old detective in disguise.

In Mister Max: The Book of Lost Things, Max Starling proved that he is more than a detective, he's a Solutioneer. His reputation for problem-solving has been spreading -- and now even the mayor wants his help.

Someone is breaking windows and setting fires in the old city, but the shopkeepers won't say a word about the culprits. Why are they keeping these thugs' secrets?
When the mayor begs for help, Max agrees to take the case, putting himself in grave danger. It's a race to catch up with the vandals before they catch him.

Meanwhile, Max is protecting secrets of his own. His parents are still missing, and the cryptic messages he gets from them make it clear -- it's going to be up to Max to rescue them.
