My favorite characters are Marilyn the incredible mongoose (of course) and Spider, Eli's eldest cousin, who will be the future CEO, but is currently in charge of the Department of Loyalty.
Overall, the book was a 3. It wasn't particularly exciting, and it didn't draw me in as really brilliant books do, but it was good and solid. And it had a cool mongoose. It was like chicken; it had that everything-tastes-like-this feel, in that there was nothing spectacular about it (except the mongoose, so maybe it can have a pinch of spice on it), but still enjoyable.
