I am pretty interested in the Franlin Expedition--I found the book because of my obsession, not the other way around.

The book is insanely thoroughly researched, at least as far as we knew at the time of publishing. Basically every body ever found on King William Island is given a name and personality in the story, and we find out how they came to be where they were found in the coming years.

That said...I don't really feel like the tubaaq really worked for me. Especially not with the massive lore dump in the last chapter trying to unravel the mystery all at once. Basically everything about the last chapter bugged me, tbh, especially the main character's resolution.
