I enjoyed this book. It was, to be honest, not my usual taste. I tend toward more realism, or the ultimate in realism: memoir. In fact, I only read King by Right of Blood and Might due to a book exchange. That said, it was really a great story, and now that I've read it, I might ease up a bit on my genre-specific bias.
OK, so the story is timely: interested in 2012? Read it. In the beginning an asteroid hits the moon, which sets of a series of climactic events that end up wiping out much of the human population. This sets the scene. Good.
The story is then centered on a King, who is faced with the opposition that is his standing. His is the story that truly drives the action, and the ravaged world that acts as the backdrop to the story is one that lends to the atmosphere.
I admire Anna Walls because I could never write something so fantasy-driven. I've tried, and it's just a place my writing mind won't go. I truly appreciate writer who can accomplish this, and do so well.
