Of the reading I did in recent years, the nerdy centre has been Brandon Sanderson's oevre. His fantasy-that-is-close-to-SciFi style and worldbuilding is not for everybody, but it has me in its grip.
While he came to wider attention with his Mistborn series and by finishing Wheel of Time after Robert Jordan's untimely death, I consider his Stormlight Archive series to be my favourite. It combines an alien world with great character development, and it is currently at the halfway point of five out of ten books. His original fantasy stories are all connected in a greater "Cosmere", which enriches reading depth. I have recently finishes reading the last story part of the Cosmere, and even with Sanderson's driven writing speed (we are talking about a guy who wrote four extra books during the pandemic) it leaves me wanting for more.
Stay epic!
