It’s another win for Chris Grabenstein! (As well as another mouthful of a title.) 12-year-old Benji embarks on a road trip challenge with his older brother Ethan, who is on the cusp of leaving for college. The mysterious, eccentric Ms. Penelope Pennypickle is a premier puzzle maker. She is offering one million dollars to the team that can solve a set of puzzles along Route 66.The book’s conversational tone, menacing villains, silly Amazing Race-type challenges and puzzles (that feel solvable by older elementary students) make this an engaging read.
Grabenstein’s older brothers took him on a cross-country roadtrip when he was a teenager. That trip inspired him to write this book. It’s encouraging to read about a sibling relationship that evolves from strained to connected.

This book is my introduction to Chris Grabenstein and I am a fan! I read this in a few hours and was captivated the entire time. The characters were relatable and fun. I loved that the puzzles were illustrated, and I admit I was stumped by one or two. I am a game and puzzle enthusiast, and this book spoke to my love of them. I will definitely try to get this book in our library and will be recommended it to teachers and students alike. I’m off to grab another Grabenstein!
