I do know that the novel makes references to Blood Prison, though it seems that the details are different from the movie version of events. Hōzuki Castle and Mui are both referenced as having been destroyed in a joint operation by Konohagakure and Kumogakure several years before this story takes place (presumably five or six years, as it states that since Mui's death the five nations have been taking turns guarding it, and this year it's Konoha's turn again), and in this novel, Hōzuki Castle is stated to be within the Land of Waves.

The Blood Prison novel was written by the same author (and is also the only film novelization to feature original illustrations by Kishimoto), so its place in canon might be a bit different, or these might just be callbacks.
