Sometimes I did feel like I was missing out on past events that kept being brought up, but I suppose that's my fault for not reading the first book beforehand. What happened in seventh grade is referenced several times, but details are not described therefore leaving the reader in the dark until they read the previous story.
I would recommend this book for 7th graders and up. Teens will enjoy this book with a computer savvy main character who's both boy and technology crazy with a good heart. Looking forward to going back and reading the first of Erin's adventures.
