In this space set adventure the universe is mostly under the control of an Empire ruled over by one mysterious Emperor and a million Prince leaders. Every Prince is genetically enhanced and linked to the all seeing, all knowing hive mind of the Emperor. Prince Khemri is much like any other Prince, but when he is chosen for a special mission which basically involves him living as a regular person without his genetic enhancements, he meets Raine and falls in love. In an area of space not under the Empire's rule Khemri realises that there's more to life than being a Prince. However the Empire is not willing to give him up so easily and he finds himself chosen as a potential Emperor candidate. This book is a little different to Garth Nix's usual thing but it still provides a fast paced adventure that I enjoyed.
