Blog Critics has posted a review of the Host (don’t worry not too spoilery if you want to read it)
Part of the review states:
"The story ends on a note of hope. It is an emotional ride from beginning to end – all 631 pages. Any science fiction fan will enjoy this story, but Stephenie Meyer may have done for science fiction what she did for fantasy when she wrote Twilight. The Host is set in enough of a realistic setting that even people who aren’t sci-fi fans will enjoy this story. You’ll want to put this one in your to-be-read-again pile."
