Half Blood takes place in a school called the Covenant. This is a school for two races, the half-bloods are the pures. The pures are created either by a god and a mortal or by two pures. Half bloods are made by a pure and a mortal. As their name suggests, they have half of the pure blood. Greek mythology whoop whoop! 
 Don't worry it's not as lame as it sounds. 
 Half bloods are considered to be less important than the pure bloods. They are never allowed to have children and they can choose to either become a Sentinel, where they would spend their entire life guarding the pures, or to become a servant for the pures. So basically, either way it goes, their life sucks. 
 Our protagonist, Alex, unfortunately for her, is a half blood. Alex isn't the usual, damsel in distress/wait for the guy to save you, kind of girl. She is independent, impulsive, and actually kind of violent, especially when someone talks bad about someone she loves. Then she turns into some kind of hyped up were-beast. 
 Only she's not sorry, and most of the time I don't blame her. This is really her only flaw. She isn't very sensitive and doesn't really care about other people's feelings most of the time, she doesn't really have time to. 
 Aiden- 
 I just couldn't resist the Hercules gif. Anyways, he obviously cares about Alex a lot, but he's not allowed to, for our precious, beautiful Aiden is a pure blood. You know forbidden love and all that. However, he doesn't need to tell Alex that he loves her for us to know that he does. 
 Then there's Seth, who claims that he just wants to get to know Alex and doesn't know about the bond. 
 That little shit is up to no good. I just know it... 
 At the Covenant, there are a lot of parties. The kids are sometimes irresponsible and don't really grasp the severity of their situation, Alex included. 
 But this is just a side effect of the half bloods having their whole life planned out for them. They know when they graduate they will be forced into a life that they might not want, and they are lashing out. This would be okay, only that Alex does it too, even when she knows that she has a more important future ahead of her. She has a "destiny". 
 All that aside, I ended up really loving this book. Jennifer L. Armentrout is such a talented author, and her writing makes you unable to stop reading. 
 The only reason I'm not giving this book 5 stars is because it is very similar to the Vampire Academy. Almost... too similar. 
 But I don't really mind it that much... 
 Also because while it has similarities to Vampire Academy there are definitely some original ideas, and I think it will go in a completely different direction in the next book.
