The Host with the Most? The movie based on Stephenie Meyer's book is almost here

The movie adaptation of The Host is coming 3.29.2013. Despite the change in hair color from palest blond, Saorise Ronan (Hanna, Lovely Bones) still looks almost ethereal and somewhat vulnerable. I guess you would be vulnerable too if the 'wanderer' trapped inside you was fighting for possession of your mind! 
Scroll down to see the new posters. Stephenie Meyer's website makes the point that this was the author's first foray into 'adult literature'. She was talking about the distinction between YA and 'adult fiction', she wasn't talking about turning to writing erotica, LOL. Her characters are still primarily youthful and the setting is sci-fi.  It still sounds like YA to me, which isn't a bad thing at all! I don't know the rules, what is YA, what isn't and why, but Ms. Meyer; I think thou dost protest too much  Btw, I know many of you know EXACTLY what the rules are, what does constitute YA.  Please let me know where The Host lands. I'll be eternally indebted.

Here's the book description. We'll see how the movie compares when it comes out in March.

Melanie Stryder refuses to fade away. The earth has been invaded by a species that take over the minds of their human hosts while leaving their bodies intact, and most of humanity has succumbed.

 Wanderer, the invading "soul" who has been given Melanie's body, knew about the challenges of living inside a human: the overwhelming emotions, the too vivid memories. But there was one difficulty Wanderer didn't expect: the former tenant of her body refusing to relinquish possession of her mind.

Melanie fills Wanderer's thoughts with visions of the man Melanie loves-Jared, a human who still lives in hiding. Unable to separate herself from her body's desires, Wanderer yearns for a man she's never met. As outside forces make Wanderer and Melanie unwilling allies, they set off to search for the man they both love.
Featuring what may be the first love triangle involving only two bodies, THE HOST is a riveting and unforgettable novel that will bring a vast new readership to one of the most compelling writers of our time.

This last poster confused me. It looks like it could be Saorise as a slightly older Melanie; the hair is blonde again. But The Host book fans can probably confirm that this is The Seeker, a very unlikeble soul. She's played by Diane Kruger who is probably best known as Abigail Chase in both National Treasure movies. The other guy in the first poster is Jake Abel who plays Ian O'Shea, in love with the wanderer (the one invading Melanie's body).

I don't know if it's YA but it's perked my interest.  It definitely has more appeal to me than any of the Twilight series, none of which I've read or seen ... even though I know some wonderful women, young and old, who are addicted to the series! How 'bout you?
