I'm not sure what I can say about "Half Blood" that hasn't already been said. If you're looking for a quick, fun read, with an awesome female main character, look no further - "Half Blood" fits the bill. This is one book that lives up to the hype.
"Half Blood" picks up where "Daimon" (the free e-book prequel available through Spencer Hill Press's website) leaves off: after Aiden finds Alex struggling against a group of daimon's. The Covenant has spent the past three years searching for Alex and her mother, and when they finally find Alex it's too late for her mother as a daimon already got to her. Her mother never explained why they left the Covenant, but she was sure that if she returned a life of servitude awaited her - she was a half blood, her mother had run away with her after taking her husband's fortune, and she made no effort to seek out the Covenant in the three years she was gone. Thing's don't look great for Alex, and upon her return to the Covenant, her uncle tells her that he's worked it out so that she was serve her step father. That's when Aiden, a pure blood that Alex developed a crush on, asks her uncle to allow him to train her instead.
Watching as Alex and Aiden, a half and a pure, train together is interesting. As a Sentinel, and someone who lost his parents when he was young, Aiden isn't one to show emotion. He's an all business type of character, but Alex seems to bring out another side to him. Their relationship changes over time, developing into something more for both of them, but since pure's and half's are not allowed to engage in relationships together, they cannot act out on their feelings as it'll end badly for Alex. Of course, the two moments in which they manage to forget about this rule you can't help but to smile.
When Alex's step father comes for a visit, trying to bring her home, he brings with him Seth, the Apollyon. There is only supposed to be one Apollyon at a time, although there has been two in one period before (which didn't end well), but you can suspect that when Alex see's his markings and the others don't that something is different about her. It makes for an interesting storyline, and much like Aiden and Alex, Seth is easy to like.
I loved "Half Blood". It is funny, it is heart breaking (especially watching as Alex broke down over her mother after her uncle delivered the startling news), and it is action packed. I can't wait to read "Pure" to see what happens next with these fantastic characters.
"Half Blood" is full of great quotes, such as this one:
"I glanced down at the dumbbell and pictured it flying across the room - at his face. But it was such a nice face, and I'd hate to ruin it." (Page 84)
