Listening to this series on audiobook is so much fun. The mysteries keep me on my toes and I love the characters. The summer camp vibe was perfect for the season and I liked how Johnson shifted settings so easily. I liked seeing Stevie's friendships with Janelle and Nate continue as well as her relationship with David. I didn't see the twist coming yet again, and I liked all the clues and red herrings thrown around in this installment. It also managed to be closed up nicely which was great. I'm excited to read the fifth one and see where Stevie's brain takes her next!
