The Host is definitely a million times better than Twilight. There is romance, but unlike Twilight, the main character is a three-dimensional person and the pag-ibig interest isn't a stalker boyfriend. In my opinion, Stephenie Meyer should write madami adult novels and stop with Twilight.
it also has romance but it is not only about that, its madami about human feelings from the perspective of someone who isn't and she is overwhelmed sa pamamagitan ng them (they ipakita motherhood, anger and strong feelings like these) the romance part is also different from twilight, they only fall in pag-ibig after knowing each other, sharing experiences etc, in twilight it was almost pag-ibig at first sight. don't expect to find anything similar between these 2 books (just that in both men are perfect XD)
