As a huge fan of the Twilight series, I had high hopes for The Host. Unfortunately, I didn't like it nearly as well. The story is excellent, well thought out and conceived, and if I had read it first, before the Twilight series, I think I may have liked it better. It seemed to me to be too similar to the Twilight books, both in verbage and story specifics. Once again, it's a love triangle. One of the characters is self sacrificing to a T, willing to give her life for others, a doctor who everyone trusts and admires because he's so noble and pure... there were so many similiarities.
So, like I said, if it was Stephenie Meyer's first book, and the only one I'd read, I think I would have really liked it quite a bit. But unfortunately, I'd already read Twilight and the comparisons are just too great. And really, how could anything that's compareD to Twilight even compare? :-)
