I wasn't sure if I was going to like this book when I dove into it (forgive the pun). It turned out that it grew on me. The first part of the book definitely feels like a completely different story from the second, and it even had inklings of space horror -- something which I appreciate and find too little of. That it was an explainable phenomenon disappointed me a little, but I still enjoyed the twists and turns the book took.
An interesting kind of touristy shipwreck exploration, history and amateurish archaeology, led by someone who is cautious to a fault, occasionally fearful, nonviolent, frustrating and who tries to be a good, safety conscious manager, but who occasionally gets caught up in her own desires. Someone who is, in other words, human. I appreciated how down-to-earth the whole thing was.
Cool. Worth the read.
