Although it was interesting having a mating-at-first-sight type of romance, I wasn't the biggest fan. I did like having a glimpse at Selenka and the Russian wolves and expanding more into that region of the world, but the romance...meh. 

Having characters who struggle with their past and believe themselves to be so eeeeevil because they've done super duper bad things can be hard to swallow book after book. Because the narrative and structure of these books and the romances can mean that you can never have the main characters be actually evil or irredeemable in any way.

Also, Ethan has light powers. That was neat.
