I read the First Light Chronicles, and was lost. Don't be fooled by the 'free' price tag; the first sample is always free, and these are seriously addictive. I defy you to read it without buying all of the Spinward Fringe series.
The writing is a curious mixture of old and new. I thought for a while that I'd stumbled upon a lost masterpiece from the Golden Age; then was brought up short by the references to quantum computers :)
Anyhow, good characters, and a cracking pace whatever they are; highly recommended.
