I started this book back when I was on vacation, in September, but it was the last book I got to and the end of my trip interrupted the awesome reading streak I was on. So I ended up pleading this book with week-long breaks in between, which I'm not sure is the best way to appreciate this particular story. It's been quite a while since I've read Shadow of the Wind, and The Angel's Game is fresher in my memory but still a ways off. I do remember thinking that Prisoner of Heaven grabbed my attention and moved along more quickly than Angel's Game. It also lacked any overt supernatural overtones that The Angel's Game had. In short, I enjoyed The Prisoner of Heaven as a sequel to Shadow of the Wind, I liked reading more about the characters I was so familiar with in the first book.
