In Blaze of Memory, Katya has been pulled from the Silence and thrown to the Forgotten, likely as a spy. But her memories have been taken from her and she does not know why she is there. Dev, a leader of the Forgotten, is determined to keep her from harming his people. Somehow, keeping his people safe turns into protecting Katya from the evil that tortured her. Katya's exposure to emotion has a profound effect on her and she is driven to discover certain truths that will most certainly affect all Psy on both sides. 
 Throughout the story, I really liked the entries that describe the beginnings of the Forgotten. Both Dev and Katya are strong, imperfect, interesting characters that had my eyes getting a little watery near the end of the book. Other secondary characters were obvious players in previous books in the series. There were some elements of the Psy world that were not well explained though I'm confident followers of the series would have no problem keeping up. 
 I can easily recommend this book to anyone who has read other books in the series. If you haven't and the Psy-Changeling series sounds interesting, I'd say start at the beginning.
