This week I have started and finished Quarantine, by Greg Egan. This is my second read of a truly awesome book. I highly recommend it to anyone who enjoys (or is interested in trying) really hard SF.
Re-reading quarantine actually served another purpose besides keeping me sane on the commute into work: I have aspirations for doing a massive amount of writing work on the wikipedia entry for Egan. I've done one or two small edits so far and wrote some speculation about some concepts in the novel.
I've re-read this whilst I await an amazon order. Richard Morgan has just released his fourth book, albeit his third set in the world of Takeshi Kovacs. Although described as both cyberpunk and hard-boiled (both derogatory terms in my book), the first two novels (Altered Carbon and Broken Angels) were good fun.
