(3 1/2 stars)The soft blue cover was the first thing that caught my attention about this middle grade book. Charming, witty and quirky, this was a delight! The Lemony Snicket-type story is told by a slightly obnoxious narrator who speaks directly to the reader and offers silly quizzes at the end of each chapter. The twins and their father are odd but interesting and likeable. They each have their own distinct personalities, interests and abilities but are still united as a family. When bumbling kidnappers take their father, the children use their unusual talents to try to rescue him.The illustrations and drawings in the margins, really makes the story. There were extra fun elements like sketches of their ideas and inventions, and crossword puzzles. I loved the design but unfortunately for me, I couldn't see several of the illustrations or the copy written on those pages. The (arc) ebook version I had kept freezing up and was so frustrating!I still enjoyed this story and look forward to more of the series from this debut author. Entertaining for kids but fun for adults too!Thank you to Edelweiss for an ebook (arc) to review.
