Forewarning, Circumnavigation is an extremely long read. I got curious after reading, and compared the length to that of the Harry Potter series. I was surprised that there is only a 4,000 word different between Circumnavigation and the entire Harry Potter series. That's incredible for a single story. It's definitely a big commitment.
That being said, it was worth every minute spent reading it. I'm currently working my way through it a second time. Everything about this story makes me happy. The writing is excellent. The places are amazing and the detail is just incredible. I really fell in love with some of the characters. Everyone in the book felt so real, and most were very well written. And finally the story is a nonstop, wild ride. As the reader I felt like I knew so much more than Trevor and his friends, but there were many times that C James proved that I didn't know as much as I thought I did.
After starting, I couldn't put it down. This is one of my favorite books I've read, on and off this site. I can't imagine the time and dedication it took to write this book. I applaud your work 150% and really appreciate the work you put into it. Really. Great work. Absolutely amazing.
