I was bowled over by this recent Goodreads review of Sockpuppet, and had to share it here. It starts:

I've seen a number of books described as geeklit over the last few years, but Sockpuppet is the first that truly delivers on all levels. An intelligent, well-crafted, superbly plotted thriller that races along, its feet are firmly and very realistically set in the digital world.

And ends in style:

Highly recommended. Unless you think a sockpuppet is actually a puppet made out of a sock. Then it might just blow your tiny mind.
