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 Chronicles of Narnia were the first series I bought in its entirety. I was enchanted by the magical worlds and diverse characters. It took me a while to collect all the books, but it was worth it!
