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?
I was gifted the whole Percy Jackson Series for my birthday one year. It helped me get back into reading. Shortly after that, I was hooked on the New covers for the Lunar Chronicles and ended up buying the whole box set. Loved it. Though I never got through Stars Above before selling it.
