Mutiny on the Globe: The Fatal Voyage of Samuel Comstock Book

This isn't a bad book. My own expectations going into the book, however, did not quite match what I found.
I picked it up to read when I saw it on display at a library. I anticipated it might be an account of a mutiny at sea, and the mutineers voyages thereafter.
It is that. For all of about two chapters, roughly forty pages or so. The book before that delves into a background and psychology of our Young Mutineer, and the circumstances and places he was in.
As it stands, Mr. Heffernan does a wonderful job of telling what we do know of the story, but the part of the story I thought would be the most extensive was temporally very short and sparsely documented. Much of the rest of the book is spent detailing two survivors left behind on the Islands with the natives and trying to piece together various contradictions in stories (which he does a good job of explaining), but it is less directly riveting than I was initially expecting.
The appendices are quite nice, including the text of George Comstock's, who was a crew member (and brother of the Young Mutineer) account that is heavily quoted from and utilized as a source.
Overall, good book, but not quite what I was expecting given the title or my general experience in the genre.
