I originally meant to do this as a new year's thing about what I had read. But I'm the worst at new years nonsense and book recommendations need no specific time. This way I can just bunch series together and not worry about what I actually read over any specific time period. (Well, this is vaguely June '17-May'18 of my reading list...so yea. Books!)
