Hush, Hush fans?

Has anybody read the Hush, Hush books by Becca Fitzpatrick?  I first found out about them when I saw a publicity poster for the first book at the school here in Turkey; they must be pretty popular if they're being translated into Turkish.  I don't know much about them, beyond Amazon blurbs, but they look similar to the Twilight series, at least in that they're about love and non-human beings.  Any takers?
