A good novel because esoteric mythology NEPHILIM, is really well developed, and that of angels and demons (hierarchy).
A novel that responds well to the question, what is the purpose of our lives? what she has sense, why are we here? namely face our fears, our differences, our vices, our failures, to go beyond materialism to be able to reconnect with the divine and reach a high spiritual level.
Why frustration because I feel that us humans are true puppets, to angels and demons. While we are endowed with free will ... Drugs you, do not drug yourself ...
Because I can not stand the clichés Good girls fall in love with bad guys! At the same time we are facing a girl half angel of light and a guy half demon, not any since it is one of lust.
And also because ... unfortunately we painfully waiting, the final straw between our two protagonists ..
I do not spolierai and would not say more ... but I think sincerely read more not only for anna and kaidan but also because I am thirsty to know what is coming in this fourth dimension ..
