Guardians of the Crystals: The Osirion Connection by K.D. Martel is a good read with a nice flow, action, and character development. A world where two races: the Atlanteans and the Osirion, share the Earth after a great flood. It's a vision of what we have and what we at risk of losing. It deals with themes like the collapse of a society, the hypocrisy that we base a society upon, and the essence of human existence and its possibility of change. A good sci-fi story isn't just about the technology - it's about the human story. This tale is deeper and more complex than most of the sci-fi that I've read in the past. A book that will linger in the reader's memory for a long time. Well worth the cover price.
