4.5 stars. Part of me really wants to give this a 5 star, just because I was emotionally happy to be reading a GOOD story after a few less-than-satisfying ones.So many people know of Kenyon's other, more popular, Dark Hunters series. Given that I've only read 1 book in that particular series, it's not completely fair for me to compare the two, but when I read book 1 of the League, I found it SO much more interesting than book 1 of Dark Hunters. I can't begin to convey just how enamored I am of the world built in The League series. Nor can I convey just how in love I am with The League's heroes. These men walk, talk and act like actual men, instead of some female author's version of how a man might behave. The characters are like a more realistic version of one of the Black Dagger Brotherhood's characters.Plus, you really can't go wrong with copious amounts of assassins and space travel. The sexual tension is perfected in these books, since you get a lot of fun lead ins and a decent payout without it killing the actual story.Hail to the sci-fi romance genre! I think I might hang out here more often!
