Yes, I read it a while back. I thought it was a thoroughly interesting story, which I sucked down like drinking a think chocolate milkshake (in about that amount of time, too!).
My impression, though, was that the author was rushed to write the story. The editing could have been better, because there were a few times I was confused/distracted from the story line by details that didn't make sense.
I don't know how she survived under those conditions for so long. I wonder still how Betty is doing and where she is nowadays.
