This is the 5th book in the Psy/Changeling series by Nalini Singh and the story of Dorian and Ashaya.
Ashaya Aleine is an M-Psy (medical) specializing in DNA. She has been forced to an underground research facility by The Council and charged with finding a biochemical weapon that will give the Psy an foothold over the human and changeling population. To keep Ashaya in line and doing what they want, The Council has kidnapped her son.
Dorian Christensen is a DarkRiver Sentinel, in every regard he is leopard. He smells like a leopard, moves like a leopard - but from birth he has not been able to shift into leopard form. Dorians leopard lives within him and has no way out - this is the reason why Dorian pushes himself to be better at everything else. He needs to be better to make up for what he feels is a disadvantage.
Ashaya helped Dorian and the Changelings rescue two human children from the underground facility. The Changelings felt they owed Ashaya a debt - this debt was called when Ashaya asked them to rescue her son from The Council.
Dorian has not been able to get Ashaya out of his mind and this is driving him crazy because the one person who loved him unconditionally, his sister, was killed by a maniac Psy. Dorian feels that this is a betrayal to his sisters memory.
Can Ashaya escape the underground facility? Can Dorian rescue Ashaya's son and overcome his hatred for all things Psy?
This was a wonderful read and like the ones before it, I enjoyed it immensely. I love the world Ms. Singh has created, it is complex and evolving. I can't wait for the next one.
I give this book and the entire series a 5 out of 5 stars.
