"Once again, Tchaikovsky performs all the wonders of the first book, while at the same time making some quantum jumps in his sequel ... the underlying message of persisting through misunderstandings, fear, and hatred until harmony and new balances are reached is not just preached, but embodied in thrills both corporeal and intellectual. Tchaikovsky's good sense of pacing and his ability to make arcane scenes and concepts vividly transparent all contribute to a winning tale ... With the guiding spirit of Poul Anderson hovering over his shoulder, and the buttressing work of peers like Vernor Vinge and Paul McAuley standing to either side, Tchaikovsky has made that rare transition from master of fantasy to master of SF."-- Locus
