I was starting to get tired of my series of teen time travel books, but I liked this one a lot by the end. The protagnoist, Tommy, is looking for something on the other side of the vortex that he falls through--the same thing that a lot of us are looking for if we travel: romance, new experience, a chance to trace cultural heritage, maybe even a chance to make a difference. In this case though, Tommy's an orphan too, and he's looking for a sense of family that he's never had. Anyway, I thought it was endearing. Since it's about the potato faminine, I appreciated every meal that I had with my family while reading it.
