(Disclosure: Eliot's a friend and he sent me a pre-release copy of Cumulus.)

Really enjoyed this book from Eliot -- he takes the concept of "absolute power corrupts absolutely" and applies it to some present-day tech trends. Cumulus is a plausible (but fantastic) extrapolation of what the Bay Area could look like w/trends un-checked. Found myself nodding at several points at some obvious worst-case scenarios.

I like it when authors tease out a what-if scenario to see where things could go, and really enjoyed Lily (the main character) and her motivations. Her evolution in particular was fun to follow.

The ending is a bit abrupt, but in the end that didn't take away from my enjoyment of the story as a whole. It's always a pleasure when authors truly understand the technology that they write about -- which Eliot clearly does. That lends a credibility to the story and to the characters' decisions that is often absent in other thrillers.
