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?
Bought a LOTR+The Hobbit box set on eBay for $20 a few months ago. They have the absolute corniest covers I have ever seen. They’re awesome.
