"I enjoyed Julian May's Pliocene Exile series and have been waiting for her new book. She is a writer of perception and power who has created an original world by a skillful weaving of archeology, mythology, and imagination." -- Jean Auel
"I've long been impressed with Julian May's imaginative and richly detailed alternate history. The care and attention she brings to her novels is an inspiration to anyone with ambitions to create a self-consistent world of fiction. Unlike so many others, she does her homework and weaves threads from real life into her tapestries of wonder."
-- David Brin
