This reminds me of the BYT series by Godbersen - in a nice way. I enjoyed having the story told from three different perspectives as I think the book would have been boring if it were up to one girl to pull the storyline along.
I've been watching "Boardwalk Empire" lately, so this book really came alive for me with the atmosphere and music from that series. Gangsters, pearls, smoking guns, and innocence. Now all I need is to get my flask engraved and a garter to hold it up.
