I'm glad that Stormlight books don't come out too often. For one thing, I want to savor the experience and thrill of new books in this amazing series. For another, I would be much less productive at any task besides reading them. Rhythm of War, the newest installment in the series, was full of just as much emotional poignancy and compelling storytelling as the previous books in the Stormlight Archive. It broadened the scope of the world and the conflict in entirely new directions, it was full of twists (a few of which even I didn't predict), and just as it went about answering key questions about the plot and the world, it raised even more.
Where do I even start with a Shannara review? Shannara is epic fantasy in the very literal sense of the word, spanning hundreds of years of in-world history across myriad series and trilogies and stand-alone novels. Perhaps Brandon Sanderson's Cosmere may eventually be larger in literary scope, but even that will likely not sprawl so much as Shannara. Where a series like Wheel of Time covers a single story arc, Shannara has era, ages, and dozens of independent arcs. Sometimes, one has to wonder if Terry Brooks can bring himself to write anything that isn't Shannara: supposedly his Knight of the Word trilogy began as something new, and morphed into a prelude to Shannara.
