Query: move over, John Grisham

Mississippi has yet another great writer to brag about. Embryo was a suspenseful, fast-paced medical thriller that kept me on the edge of my seat. The technology used to grow embryos outside the womb was explained in layman's terms so that I pretty much understood it. And like great science fiction, it seems to follow real-life scientific developments (i.e., Dolly the sheep). What a scary thought that events in this book really could parallel real life! Charles Wilson always gives me something to think about. In addition, toward the end of the book, just when I thought I had it figured out, the plot took a totally unexpected turn. That shows a truly great suspense writer. I agree with reader from Newport News that Wilson can easily join the ranks of Robin Cook and Michael Crichton.
