I'm a slow reader and that frustrates me so I end up stopping a lot of books that I'm enjoying. That hasn't happened for The Witcher series. I'm in the 4th novel now, though I will say the first novel is a very slow read compared to the superior short story compilations.
I've also recently purchased Wicked and Weird, the autobiography of Buck 65 and Abomination by Gary Whitta.
I'm also in the mood to reread something old. Thinking it'll be either Harry Potter (start with the first and see how far I get), Life of Pi, or The Catcher in the Rye. Now that I think about it, I haven't read Catcher since before The Ocean is Full of Bowling Balls leaked. I should reread them and see how that affects the experience.
