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?
Hard to remember. It may be the whole of Sherlock Holmes when I was a kid of 8 or 9. Foundation also at 9, Dune may have been a little while later.
