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 Dark Tower by Stephen King, I bought the whole series just based on few reviews I’d read, didn’t know what to expect. Fortunately, Stephen King didn’t disappoint me.
