As what will probably be the final book in the series, what could easily have been a bittersweet book (by any standards) ends up being a surprisingly heartwarming affair.

... Of course, seeing as this is a book about Caine by Matthew Stover, one must remember that everything is relative. One of the most heartwarming and tender moments of the entire series is framed with the story of a person who suffered even more than Hari/Caine.

Caine's Law continues the non-linear approach from Caine Black Knife, but cranks it up to 11 with at least five different threads (and a few one or two chapter fibres) that don't necessarily converge (There is a reason that the most used phrase in the book is "It's complicated").

Does Caine's Law provide true closure to the story we have read over the years? No, there are lot's of unresolved issues at the end of the book. And that's okay. Because this isn't a series about Home or Earth/Hell. This isn't even a series about the adventures of Caine.

This is a series about Hari/Caine/Fist/Shade himself, and Caine's Law definitely resolves that. Hari/Caine/Fist/Shade, and the reader, finally understand him, as much as anyone could.

And bonus points for managing to introduce a character who is even better at the Role of Caine (as of Heroes Die) than Caine himself was.
