I just finished Shanghai Girls last night. It was good, although there were times I wanted to reach in and shake some sense into one character or another! But the story itself was very engaging. I was pretty pissed about the open ending until I discovered this is actually a 2-book series, with Dreams of Joy as the continuation of the story. Not sure yet if I'm going to read it, though.
Up next is either Elizabeth Street or The Invisible Bridge.
