“An Enemy at Green Knowe” by Lucy M. Boston. Was mentioned by Gemma Files, and it was short (being a MY novel) so I got it out of the library and read it.
“M is for Magic” by Neil Gaiman. Troll bridge was awesome.
“BlindSight” by Peter Watts. Signed by the author! I had to look up a lot of words. One of the really bad openings we discussed at the workshop at SFContario was the wakeup scene, and this novel has something like 50 pages of one of those. Though waking up conveys so much information, here it works.
“Percy Jackson: The Titan’s Curse” by Rick Riordan. I’m somewhat amazed that I read four books this month, even if three were meant for pre-teens.
