K-Gr 3— Derting and Johannes highlight the previously unknown fourth little pig, Penny, in this engineering "tail." Sister to the famous three little pigs, Penny is determined to shine through her engineering expertise. When Wolfgang, the big bad wolf, wreaks havoc on the pigs once again, Penny arrives to assess the damage and help her brothers design a wolf trap. The dialogue brings this extended fairy tale to life and will easily entertain and interest young engineers. Marks's colorful and eye-catching illustrations will have readers poring over the pages. VERDICT An excellent choice for elementary collections, and especially recommended for STEAM shelves.— Brittany McMahon
