Mistborn is currently 2 series. Eventually, I believe, it will be 4. The first is the trilogy (The Final Empire, Well of Ascension, Hero of Ages). The second series is called "Era 2" or "Wax and Wayne" after the main characters. It advances the setting established at the end of the first trilogy by 300 years. The final book in this era is out in November. Eventually there will be an Era 3 which I have heard is possibly 1980s-ish cyberpunk inspired (with magic, of course), and then Era 4, which is going to be more "magical sci-fi" future. These later eras will end up meshing with later eras of the Stormlight Archive. All this is inspired by things the author has said are his plans, but it's obviously going to take a while. Mistborn Era 1 is chronologically before Stormlight Archive books 1-5.Looks like there are more Mistborn books than the first trilogy......Now I'm really unsure what to read!
Just finished the Elenium by David Eddings. Started the Tamuli.
Haven't read them since the 90s maybe early 2000's.
Not as good as I remember still enjoyed them though.
Back when I was a teenager in the stone age, I loved my Analog subscription my grandparents bought for me. But I could never keep up, even with a teenager's free time. Can't imagine trying to keep up now as an adult...I've finished Day of the Tiffids and Semoisis for the Stellaris book club. We meet on their official discord server.
Trying to read more of my Analog magazines, I'm too many issues behind right now.
