K-Machines is more disappointing than Godplayers not just because the questions still have not yet been answered and the background explained, but because the distractions from the questions here are not as interesting as in the first Book and are not really explained in themselves. -- Sam Lubell, SFRevu
A mad fusion of Alan Moore's Promethea with a half-dozen Greg Egan novels (tossing in a bit of M. John Harrison's space opera Light [2002] for the Jamie Davenport segments), Broderick's duology is an Ouroboros Worm that ends up eating itself but in the process giving birth to a miraculous and hopeful new cosmic egg. -- Paul Di Filippo, Scifi.com
...in the final analysis, I think, this Book is really to a great extent a commentary on SF, and on the love we (the Author most certainly included) have for the genre. -- Rich Horton, SF Site
