There really aren't enough good comments or adjectives in the dictionary to describe this book. I bought it on a whim, if I'm being honest, not really being a sci-fi fan, and found myself totally and completely loving it only a few pages in.
While the storyline might not be the most obscure, original thing in the world, (imagine Invasion of the Body Snatchers, except this time we lost), Meyer does succeed in giving it a new, surprisingly fresh, twist. The storyline is basically centred around a very experienced 'Soul' (Wanderer) who finds sympathy and friendship with her host (Melanie) who refuses to fade away. And also a strong love for someone she has never met. The two team up and track down the man and Melanie's kid brother, but not all goes to plan, as you could imagine...
Although, on that note, I'd like to say that the characters are the main driving force behind this novel. I always love Meyer's characters - I've read the Twilight series, of course - but these new set really impressed me. Wanderer, as I said before, is the main protagonist, who is likeable in herself just for being kind in nature, but Melanie is also likeable for her strength and stubborn attitude. They completely parallel and contrast each other, which I personally loved. And then there's the boys... Jared, who is the main guy character, in a sense (not for me though, thank you very much) and is who Meyer described as the 'tough' one. And then, of course, there is Ian. I love his character too much for words, and I think he's the real reason as to why I love the story so much...
Anyway, overall, it's obviously a 5/5 for me, and I'd recommend it to anyone - sci-fi fan or not.
