An unimaginative story with far to many similarity's to LJ smith's Greatly superior The Awakening (The Vampire Diaries)
The Characters are unchanging with a mildly robotic quality. the 'good guy' is not only controlling, manipulative, overbearing and a liar but he has murdered and whilst he claims to regret it he shows no remorse and can't really be trusted anyway.
The female lead is somewhat lacking in personality and has a unrealistic and frankly quite bizarre 'put everyone first' 'nothing for me' 'I'm important' thing going on which works for Wanda the alien in host but Bella is supposed to be human.
the series doesn't get better ether, it concludes with a lets all be friends, every things okay anticlimactic discussion on the battle field.
Ignore the hype and skip the sub-par crowd pleasing introduction go try one of the decent books 'further down the rabbit hole'
The characters in other books of the genre have so much more depth more detail more humanity I feel sorry for those who like this and have not read something better as even the books closest to it in quality tower over it and yet it is inexplicably popular.
that one star I gave it is one star to much.... aaaand queue the hate mail
