Pretty Girls

Pretty Girls is the first novel I have read (well, listened to??)  by Karin Slaughter. I liked it a lot. More the charactarisation rather than the plot (which was a bit farfetched). There is what I assume a story called Blonde Hair, Blue Eyes as a bonus in which we see the absentee character (she has disappeared when our two main characters were teenagers) and what I think are her last moments. I didn't continue with it though not only because the novel has already ended and I knew what happened to her but also because I was not as interested in her as I was with her two sisters.
