Bungie doesnt even care enough about their lore to make sure they dont contradict it. On the lore tab for one of the Curse of Osiris sparrows it has a transcript from the Consensus session where Osiris was banished. Then, more recently, they released their comic showing the same event, but it's entirely different in how it happened. When called out on it, Narrative Director Margaret Stohl said that all grimoire is 'folklore' and subject to change. If they cant keep things straight between their own game and a comic, I have little faith a novel would be any better. You want a novel? Go wade through the slog of Fanfiction. Most of the time it's garbage but once in a while you find a decent writer.
