Coalescent isn't bad at all ... I couldn't help tearing through the whole thing in just a couple of days ... but it feels somehow in need of a polish, of tightening up, and then it would be a very much faster-moving beast altogether, which for a conspiracy novel (and this is a conspiracy novel, albeit a very unconventional one) is something of a must. -- Stuart Carter, The Alien Online
Coalescent is still recognisably hard SF, but the characters are more closely observed than usual... -- Jon Courtenay Grimwood, The Guardian
Coalescent is a long first chapter in what promises to be a fascinating and thought-provoking story about the destiny of mankind. -- D. Douglas Fratz, Scifi.com
It is a triumph that the Author managed to squeeze so much space-time into this novel. -- Lucy Ward, SF Crowsnest
