I just finished reading this book and it was amazing! it was much lighter than 'The Destiny Of Violet And Luke' but still had some dark and sexy themes. I loved Micha, he was sweet, sexy and genuine, and his love for Ella was inspiring. I also liked Ella, she was a bit of a bitch at first and I wasn't so sure about her, but then as the story progressed I understood her reasons for acting the way she did. I think Lila and Ethan were really cute and I can't wait to read 'The Temptation Of Lila And Ethan'!
I think this book suites 16+ but I guess it depends on how much you feel comfortable with sexual themes, although I don't think anything was too graphic, but maybe that's just me :D
Anyway, read it and let me know what YOU think!
