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 Cairo Trilogy by Naguib Mahfouz. Not so well known these days, unfortunately, except in Egypt where they love him. He won the Nobel Prize in 88, and I can’t recommend him enough, especially The Cairo Trilogy, which starts with the book Palace Walk.
