Brandon's an enjoyable new type of character. He is a very bright boy who has power of the winds. His main motivation is solving the mystery of his brothers death/disappearance. More than anything, it appears to have given him an innate curiosity and desire to question the events surrounding him.
Overall, its a refreshing change of pace from the character motivated solely by some type of oppression or a bad guy forcing the character to be a hero. Not that I mind those types, it's just nice to have a little variety in protagonists.
A great continuation from Alpha in the Omega. The journal chapter was certainly an interesting look into Jesus' mindset.
Then of course you have Brandon developing even more. By the end of the book he has finalized his resolve and I can't wait to see what he does next.
