Pyri has spent a year being experimented on by a cruel Devori. When she's rescued, she finally thinks her ordeal is over. Quickly separated from her best friend, Pyri finds herself at the mercy of not one, or even two Adosian aliens claiming her as their mate, but a pack of five! They're dominating, controlling and don't seem to realise they're pushing her away even as they try to win her heart. Because there's a caveat to Pyri being here and that's the Tessans. They've given the Adosian leader and his pack a cycle to win her willingly, or they'll come and free her by force. Pyri has no intention of giving into these males. They're bully boys. Arrogant, dismissive and foolish enough to think that they can intimidate her into loving them. As Pyri fights them tooth and nail, Talis, Adaran, Nadan, Kemar and Thelan begin to realise human women aren't as easy to control as their own and, maybe they don’t want to. More, as she leads them on a chase they begin to see the cracks in their society, cracks that Pyri refuses to stop exposing until their whole system of domination falls down around them. With the Adosian females on Pyri's side, Talis, as leader, must make decisions that could bring his whole world to the brink of war. If you like books with dominant aliens who learn to bend, and strong females who will fight for what is right, then you'll love this book. In this story, all of the love is only headed towards the heroine. Warning, each book is a standalone story, in as much as the heroes and heroine will have a guaranteed HEA at the end. However, as much as I would like to write standalones, this is a part of an overarching story which begins in the Renegades series, with The Mercenary's Dawn. It continues through the Warriors series and is picked up here. While Warriors deals with more intimate stories, Rulers tackles the growing political fallout from the Renegades series and begins building towards the coming final conflict.
