Have anda read Hush, hush sejak Becca Fitzpatrick? It's lebih about fallen Bidadari then it is just Bidadari but it works right? Anyhoo it's really good, if anda haven't read it anda should give it a try. ^^
Hush hush sejak becca Fitzpatrick, halo sejak Alexandra adornetto, fallen sejak Lauren kate, a little bit of Angel stuff is in city of Bones (mortal instruments series) ok that's about it
