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?
Harry Potter, though it was one book at a time. I’m in the generation that aged with the books. My sibling and I would pool together our money to get each new book on the release date.
I stood in a looong line at Barnes and Noble for my preordered Half Blood Prince.
