The whole Rifters trilogy (quadrilogy?) is amazing, Starfish is actually my least favourite of the Rifters' books but still really good.
The villain Achilles Desjardins (I don't think he shows up in Starfish? been some time since I read it) is possibly one of the most villainous and sociopath characters I've ever read in a book.
His Sunflowers series is great too. Maybe my favorite (after Blindsight, of course).
