Security Squad (Mars Cannon #3)
Nicolette Pierce

Wrong.
So very wrong.
When the arcade wall is vandalized repeatedly, Mrs. Janowski calls the squad for immediate action. With Aaron’s help, they decode the message on the wall, leading them to a seedy bar where danger lurks. The bar’s parking lot is full, but where are the customers?
Mars has her own problems to work through. Evan and Brett . . . and the envelope. Mars discovers a secret that Evan’s been keeping, threatening their new relationship. And Brett . . . God, she doesn’t know what to do about him. But she’ll have to figure it out, and soon.
