Another one. Yep. Underground may be her best yet, although her "monster" was rather hard to accept at first. Throughout the reading of the book, the line, "Alligators in the sewers," spoken in the little girl's voice from E.T. kept going through my head, and it was darn distracting.
Other than that, though, the main character, Harper Blaine, is extremely well-developed and enjoyable to read. She is strong, yet sympathetic. Her needs and wants are clearly demonstrated, along with her determination to do the right thing despite what it may cost her personally. It was also nice to see the new love interest developing. Oops, that was a touch of spoiler, I guess.
All in all, a good read.
