The Bletchley Riddle by Ruta Sepytus and Steve Sheinkin

 

Historical fiction and mystery are expertly combined in this fast-paced book set in the summer of 1940. It begins with Lizzie on a ship bound for her grandmother's home in America to avoid the war. Lizzie escapes from her guardian just before the ship sails, proving herself to be no ordinary 14-year-old girl. She stays in England with her older brother Jakob who is covertly working as a code-breaker at Bletchley Park where Alan Turing and other real historical figures are frantically cracking Nazi codes. While Jakob works on the Enigma machine codes (fascinating!) Lizzie is solving the mystery of her mother's disappearance in Poland just as the Nazis invaded. Lizzie provokes government agents, works as a messenger at Bletchley Park, and evades her grandmother's attempts to retrieve her yet again, all the while solving mysterious codes in messages seemingly being sent by her missing mother. It's great fun and there is much to be learned about the potential Nazi invasion of Britain during World War II. Pair this with Enigma Girls by Candace Fleming and Spying on Spies by Marissa Moss and Radar and the Raft by Jeff Lantos for readers of any age (adults included) who want to know more about this time period. Septetys and Sheinkin are top-notch writers for young teens and pairing them up is a big treat for readers. 

Worldwide Crush by Kristin Nilsen

Texts, song lyrics, letters, and short chapters make this breezy, funny story about a 7th grade girl with a huge celebrity crush an appealing addition to romance books for middle school (and younger middle grade) readers. The story is inspired by Nilsen's girlhood crush on Sean Cassidy and all those strong feelings are there in the story of 7th grade Millie, whose crush on teen superstar Rory Calhoun leads her on a quest for concert tickets and later on a family whale watching vacation to Rory Calhoun's hometown. The ending is utterly perfect and the audiobook read by the author is a delight. In a publishing world where humor is hard to come by, this was a fun read and kids need FUN. Truth be told, Gen X librarians will enjoy it as much as the kids. For more on Sean Cassidy crushes and Gen X culture, check out the Pop Culture Preservation Society podcast that author Kristin Nilsen co-hosts. Recommended for grades 4-7. (It has a couple of humorous uses of swear words but I think this book probably has the most appeal to the younger end of the age range.)
