I think whether or not it makes sense to read the novel really depends on: A) whether you can separate the canons in your head, and B), whether you enjoy the character types and the relationship dynamic in the novel. For me, the answer to both questions is NO, so. Simple. ;-)

(Sure, if you think it makes sense I am happy to link this post to the comm! I thought the audience might be a bit too specific - people watching the series who are contemplating picking up the novel... ;-) )
