Dan Simmons - "Ilium" (A sci fi book based on a futuristic re-telling of the Illiad. Winner of the Locus Award for best science fiction novel of 2003.
Re-reading "The Diamond Age: Or, A Young Lady's Illustrated Primer" by Neal Stephenson. A futuristic/nanotech adventure - pretty amazing view of the non-so-distant future.
Both highly recommended.
