The structure and just the overall quality of the writing was much improved from the first book, imo. Each of the three books were pretty interesting and it ended on the most interesting one. The second one dragged and featured another damsel in distress along with a plot that was fair less compelling than first and last. But it’s 160 pages so the “drag” didn’t last long at all, anyhow. Some really cool lore was divulged, Stormbringer revealed more of its... character? Definitely will continue to the next book.

Ps: It was still hampered by some pretty overt sexism but I suspect that’s going to be the case in all lit from this time period. If that kind of a thing bothers you a lot, take note. Probably not for you and probably not going to get better considering literally every woman who’s appeared is there in service solely to further characterize a dude; whether it be hero or villain.
