Not sure I finished this. It’s a “choose your own adventure” (ambitious). A note at the beginning says you can also just read it straight through. I made a “choice” near the beginning that propelled me close to the end and there seemed to be plot points I had missed. Was this because I was reading it on an old Kindle? I hit a few “error” pages saying go back. One chapter was there twice. Was this part of the story? Ultimately confusing, too bad because I really like Shepherd’s stuff. I may try to read it again in hardcover.
