This is a monster/alien romance that is a little on the darker side. I thought it was interesting, and thankfully, nothing too triggering actually happens (

The beginning part has a scene where the Iriduans use a machine to probe inside Claire's uterus that was the most disturbing part to me.

). It's mostly about the setting and the love interests having to learn about each other and how to escape together. It has a twist on the fated mates trope, too. 

Thrax is the result of a different alien species, the Iriduans, doing genetic alteration experiments to create the ultimate fighter/weapon. His body and mind are altered from his previous form. 

Claire was well-developed I thought. She is open to alien romance because she's read those kinds of books, but she still has to get used to just how monstrous Thrax actually is. I appreciated that even though there were things about him that were off putting, she knew his body isn't his fault because the Iriduans made him that way. 

For those that may be squeamish about body fluids... 

While Thrax and Claire are trying to survive on the run, Claire refuses to eat the eels that Thrax eats. Thrax's "gift" to feed her is his seed, if you know what I mean. She's thinks it's yummy. 

I am looking forward to reading more in the series. I didn't like this one as much as The Chameleon's Mate (just because this one was a little darker), but I still think this author is creative and writes well. I will be glad to see how the rest of the universe she's created plays out.
