In the end I enjoyed this a lot but my feelings about it fluctuated pretty wildly as I read. It ended up not being what I expected--I'm not sure why but I expected magical realism. Instead it's a mystery adventure. Odd to read this in 2021, from the perspective that big tech is a harmful force; I kept expecting the enthusiastic big tech employee to be revealed to be sinister--but she's not, because this was published in 2009-ish, when I think we all felt more positively toward the internet, Google, and big tech. There are a few really lovely lines about friendship sprinkled throughout.
