A review by cavalary
A Calculus of Angels by Greg Keyes

4.0

The ideas are certainly interesting, though I'm not exactly fond of the whole religious note. The writing can occasionally leave a little to be desired, but there are also really nice moments, especially during dialogs. In all, not exactly something I ended up being enthusiastic about, but a good book nevertheless, and one that I'm sure was a whole lot more work than it appears, as alternative history always is, even when you don't try to turn all known science on its head, create your own and actually have it make sense while still roughly sticking to the world we live in!
