The Covenant Series by Jennifer L. Armentrout is awesome! Who doesn't love the Greek Gods and thier crazy kids!! The Hematoi are the result of God and mortal. Two Hematoi can produce a Pure while a Hematoi and mortal produce a Half-Blood. Pures and Half-Bloods do not mix!!
This series shows the seperation of classes within this society and how it can shape these kids' lives. Alex is a Half and can't follow any of the rules to keep her out of a life of servitude. Aiden is a Pure and is absolutley perfect. Alex has a major crush on Aiden but rule #1 is Pures and Half-Bloods can't be together.
To throw a wrench in everything you get Seth. The Apollynon or God Killer. There is something about Seth *sigh* He shows up and wants Alex too. The nice thing about Alex is that she is not a damsel in distress. She is training to be a Sentinel and can kick butt with the best of them.
I would give this series a 4.7 and I going through withdrawls waiting for the next book to come out. Jennifer L. Armentrout definitely does a great job of leaving you wanting more.
