Half-Blood (Covenant #1) by Jennifer L. Armentrout
The Hematoi descend from the unions of gods and mortals, and the children of two Hematoi-pure-bloods-have godlike powers. Children of Hematoi and mortals-well, not so much. Half-bloods only have two options: become trained Sentinels who hunt and kill daimons or become servants in the homes of the pures. Seventeen-year-old Alexandria would rather risk her life fighting than waste it scrubbing toilets, but she may end up slumming it anyway. There are several rules that students at the Covenant must follow. Alex has problems with them all, but especially rule #1:Relationships between pures and halfs are forbidden. Unfortunately, she's crushing hard on the totally hot pure-blood Aiden. But falling for Aiden isn't her biggest problem--staying alive long enough to graduate the Covenant and become a Sentinel is. If she fails in her duty, she faces a future worse than death or slavery: being turned into a daimon, and being hunted by Aiden. And that would kind of suck.
I thought I could not love this series more but re-reading it made me fall in love with it all over again. I love the characters, the story and how Jennifer L. Armentrout always manages to surprise me. Alex is one of the thoughest heroines in YA and I love her courage and her "sass". Aiden is a sweetie and a really great guy but something makes me not like me. I think it is just that, even though I now know better, seth is my kind of guy. His sarcasm and everything that comes out of his mouth is priceless. Caleb is also another great character. A true best friend. This first book in the series was interesting with a few surprises and a couple of really hot moments that just make you fan yourselves.
