X-link to the DRM-free megathread for the new Humble Bundle:
Humble Book Bundle Murder & Mystery presented by Open Road Media chock full of backlist mystery/thriller novels which includes a couple of sfnal technothriller offerings from Greg Bear (
ISFDB,
Wikipedia) and William Shatner (if you're reading this thread, you know exactly who he is), which may be worth it if the rest of the bundle holds appeal.
