A few years ago, I spent most of my savings on The Lunar Chronicles by Marissa Meyer (Cinder, Scarlet, Cress, Winter, and Stars Above; I didn’t get Fairest), read them all, and loved them…though I didn’t reread them and sold them some time later.
And what was the first series you spent most of your savings on?
The “Corum” series by Michael Moorcock. “Conan” by Robert E. Howard. “Elric of Melnibone” by Moorcock. All of these when I was 13 so 1973.
