A Scanner Darkly by Philip K. Dick: One of my favorite of Dick's novels. It's SF about the drug culture surrounding a new hallucinogenic, told from the perspective of a narc slowly losing his mind to Substance D. Like all of Dick's work, it questions reality and morality. Dark, but also with an edgy sense of humor to it.
Warchild by Karin Lowachee: I pimp this book out to everyone and anyone. It's hands-down the best SF to debut in the past 10 years. Very much a deconstruction on the space opera genre. The real strength of the novel's in its characters. They are realistically portrayed, everyone flawed and damaged to some degree. And the antagonistic is the only literary character to make my skin literally crawl and send my heart rate racing. Gritty, dark, pulp science fiction at its best.
The Dark Glory War by Michael A. Stackpole: Nice start to an even better fantasy series. Like Martin's Song of Ice and Fire, the book is a deconstruction on typical epic fantasies. You won't see the end coming, I promise you that much. And the rest of the series is pure gold as well. Very underrated fantasy.
The Death of the Necromancer by Martha Wells: Steam fantasy with a Victorian-esque setting. Again, great characters and a unique world make this one a very interesting read. No big surprises at the end, just a solid, well-written book in a genre that can get a bit trite and long-winded at times (and I say that as a fantasy fan).
A Talent for War by Jack McDevitt: This kicks of McDevitt's new series about an archaeologist in the space age. It starts a bit slow, but the central mystery of the plot is very engrossing and the characters grow on you over time. I found myself unable to put it down, forgoing sleep just to find out what was going on.
Already Dead by Charlie Huston: Bit of an urban fantasy/vampire novel to change things up. NOT a book for Twilight fans. Huston's vampires are murderers, liars, gangsters, and world-class manipulators. In other words, their people allowing their vices to rule them. Even the main character, our supposed hero, isn't really a great person. Nice book to read if you're tired of the poetic, sympathetic Anne Rice-style vampires. Huston's vamps are often ugly and mean, even the nicest in the lot.
