This reminded me a lot of the Magic Treehouse series, but beefed up for older students. I could see this being a long-running series akin to that one, but tackling bigger issues, cultural standards, historic eras, and topics more suitable for middle schoolers.

This was a really well done children's novel, it had that element that worked with talking to kids with deeper topics and about other cultures. I thought Tim worked as a main character and enjoyed going on this journey to Ancient Rome with him. It was well written and I wanted him to succeed in returning home. Deborah Lyon has a great writing style and am excited for more.
