I'm currently reading the Wool omnibus by Hugh Howey. It's pretty decent I've been making very rapid progress as it's been too hot to sleep here recently now the summer has arrived.
I haven't seen the Apple show, but maybe I'll watch it in the future when I've finished all the books (I had Shift and Dust as well).
I started with Guards! Guards! and then continued from the beginning after that (more or less... I accidentally read Wyrd Sisters instead of Equal Rites, so a little bit out of order)
