Zoe and Digby are back at it again, but now, everybody is asking them if they "are together" because the school has been carpet bombed with pictures of them making out in the grass outside a weekend party. Zoe is embarrassed and manages to maintain her dignity by wearing loose, mud-colored hoodies with headphones on her ears to hide from the many derogatory comments that people in the hallways are making about her. Digby remains determined to find out what happened to his sister, and ropes Zoe and their friends into helping him. As time grows short, Digby resorts to theft in order to get the research results he needs to trade for information about his sister.
Although Trouble Never Sleeps isn't as funny or engaging as the first two books in the series, it still contains all of Digby's outrageous stunts and ridiculous ideas. Zoe has several decisions to make including whether she will spend her senior year at a prep school in New York and live with her father, raising the question of how she will tell everyone she is leaving, especially Digby. The heart of this book, as with the others in the series, is Zoe's understanding of quirky Digby and his deceptively strong feelings for her. Overall, Trouble Never Sleeps is a satisfying ending to the three book Trouble series. ( )
