This is a great anthology from Book View Cafe. Like its "companion volume" from BVC,
Dragon Lords and Warrior Women (which is a multi-genre collection of fantasy short stories),
Rocket Boy and the Geek Girls is a collection of science fiction shorts that have been previously published elsewhere. The stories are mostly space opera, hard SF, or cyberpunkish, some with modern or near-future settings and some set far in the future.
There were only a couple of weak stories in this collection, but most I enjoyed very much. Since this is an ebook edition only, I'd recommend it highly for any SF fan with an ebook reader, as you can't go wrong for the price.
