My fave out of the three because we get some bad boy action.  I believe there is more to come because even though we get a HEA it's pretty clear the FMC isn't finished claiming her pack. So, I'm really curious to see where the author takes this because most of the past three books were spent on a war campaign.

There is some torture, mutilation, and religion fueled shaming so take care with the TWs.

Also, there is MM action but if you've read the first two books that shouldn't really be a surprise.
