I liked Oppel's books about the bats and having just seen the British National Theater's beautiful production of Frankenstein with Johnny Lee Miller & Benedict Cumberbatch, I was ready for more Frankenstein. This prequel to Shelley's book proved to be just the thing. Written for YA, the plot was a bit predictable, but it was a fun romp through references to Mary Shelley, her friends, and historical figures of the time. I read it with my computer close at hand so that I could look things up. He included interesting details about the state of medicine at the time, as well as the alchemy and metaphysics of earlier times. There was some romance between Frankenstein and his young cousin Elizabeth, whom he marries in Shelley's book. I found the romance scenes annoying, but it had to be done if it was going to be true to Shelley's plot. All in all, a fast and enjoyable read.
