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?
Not as a bundle but I bought and read A Series of Unfortunate Events and Harry Potter as they came out. It was so exciting to wait for the next book to be written and then translated and published.
