Review: If You Liked Choose Your Own Adventure, You Will Love Case Closed! - Carlos' mother is a detective, but her agency is struggling to stay afloat. To make matter worse, she is sick with the flu and can't begin the investigation for her latest case which is identifying the person sending death threats to Guinevere LeCavilier, a wealthy older woman. Carlo's mom asks him to call her partner Cole, but Carlos decides to take matters into his own hands and recruits his best friend Eliza to join him. Accompanying them is Frank, Eliza’s annoying and obnoxious six year old brother. Will Carlos, Eliza, and Frank be successful in cracking the case? Well, that all depends on the reader who must help them make choices and solve puzzles to find the perpetrator. Growing up, I devoured the Choose Your Own Adventure series because I loved having a role in the outcome of the story. Mystery in the Mansion, the first book in Lauren Magaziner's new Case Closed series transported me back to my childhood and I must share that I love her format even better! Why? When readers come to a part of the story when they must make a choice, there may be two, three or even four options from which to choose. In addition, readers may be required to solve a puzzle to identify the next page that will move the plot along. And while some puzzles are simple, others prompt readers to get out pencil and paper, brush up on their math or even call in for help (Confession: I had to seek my husband’s support a few times). After finally solving the case (Yes-it took me a few tries), I went back to the beginning of the story to start over. I became quite addictive to discovering if there were multiple good endings but even a wrong turn was fun because of Lauren Magaziner’s creative and humorous plot. Not only am I excited to share this original new series with students, I believe it would be a great class read aloud and in a recent tweet, Lauren Magaziner provides some read aloud tips for teachers. And the best part of all-Case Closed is a series! Looking forward to more adventures with Carlos, Eliza, and of course, Frank’s hilarious antics!
Review: Fun for any age - My 14 year old got this for a book club. It was fun to read and can be reread many times because you chose the outcome for the characters.
