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?
E.E. Smith, I am not sure if I completed the Lensman or the Skylark series first. These were much more popular in the early 1970s, when I was a tween, than they are today. Also understand that in those days series sci-fi wasn’t all that common, most sci-fi novels were standalones.
