After reading On the Calculation of Volume I for my book club, I immediately went out and got II and III so I could jump right back in. Book one had a real arc and I was wondering where Balle would go with book two. I found it hard to imagine. But sure enough, books two and three go to quite different places (literally) from book one.
Spoilers for both books follow.
Craving the expected passage of time through the change of seasons, Tara, the narrator seeks to create them for herself by traveling to various locations in Europe in a sequence that approximates the seasons she thinks should be happening at the time had time continued to progress normally. While I don't think I, personally, would have sought out winter (the first season Tara chases), this book captures much more what I imagined myself doing if I found myself in the circumstances when I read the first book. I thought, I would just go someplace. Start moving. Travel. I travel alone frequently and and I love meeting people on the way and making friendships that only last a day or a week. One thing I kept wondering as I read the first book was if I could do that forever – if that would be enough to stave off loneliness. (Another thing I thought, which has not been addressed in any of the first 3 books and seems unlikely to come up now, was that I would get a pet. You'd have to find one with the right temperament – i.e., a cat like my Little Hans, who loves everyone immediately – but I think that could go a long way when it comes to keeping company.) Anyway, travel seemed like the natural thing to do, and that is what Tara does for much of book two. But eventually she tires of traveling and attempting to recreate the seasons, and she settles down in Dusseldorf, where she begins to study – developing a somewhat bizarre obsession with the Romans and their contemporaries.
Book 2 ends on a sort of cliffhanger, which becomes the arc of book 3: Tara (and we the readers) discover that she is not the only one stuck in this time loop. Oddly, I found parts of book 3 a bit of a slog. I say oddly, because the introduction of another character seems like it should make things more interesting. On some level it does, but a lot of exposition was required at the beginning, with Tara recording how her new companion spent his stuck time. This changed the quality of the narrative quite a bit compared to the earlier books. The "chapters" (days recorded by Tara) are much longer while we learn about how they met and catch up on the years' worth of days. But then book 3 took a few more twists and recaptured my interest. Now I'm stuck waiting until April when I can read book 4.
