While not enjoying "The Host" quite as much as the Twilight series, I still found "The Host" to be a very engaging read. Aliens have been using human bodies as hosts and now there are hardly any humans left. Wanderer is put into Melanies body but Melanie refuses to fade away completely - so Wanderer becomes increasingly influenced by Melanie. It is an interesting read as you develop empathy for both Wanderer and Melanie; and the tricky situations they must navigate in this new world.
