Off to a good start. I'm interested to find out what "the incident" was that got the twins in therapy and separated. There was one thing that distracted me from the story, but hopefully it doesn't continue as the book goes on. Initially seems to read to a younger audience, like a teenager, but may just be because the twins appear to be early twenties. I enjoy mysteries and while twins have been a bit overused in the past, I hope the author has found a fresh plotline.
