This sci fi anthology is stronger than most I've read. As with all anthologies, for me there were stories I really liked, some I didn't like, and some I lost interest in after the first several pages. However, overall I found most of the stories engaging, and I was impressed by the skill of the writers.
It's true that a few of the stories give the impression that they were rushed a little to meet the book's deadline, and could have probably used a little more "baking time in the oven."
Sci fi, as portrayed in this anthology, is maturing - interesting plots and ideas are still there, but there is also strong character development and psychological depth.
I am starting to keep an eye out for books edited by Johnathan Strahan. I appreciate that he doesn't seem to go out of his way to find stories where sex, language, or violence overshadow good storytelling.
I found the following stories especially interesting and impressive in their skillfulness: "Ass-Hat Magic Spider" by Scott Westerfeld, "Cheats" by Ann Halam, "Anda's Game" by Cory Doctorow, "Sundiver Day" by Kathleen Ann Goonan, "Lost Continent" by Greg Egan, and "Infestation" by Garth Nix.
