Recs if you like Slow Horses (Slough House, #1)...

The book girlies are seeing their favourite characters on screen this year so if you didn’t know or want to be ahead of the game and prep, this list is here. This list includes tv adaptations and movies so if you’re curious make sure to see if it’s streaming or theatre release.

P.s. I’m including books whose adaptations already came out this year so far

Inspired to create a list by a post from @mmyth, I thought it would be nice to have a list of quest books you can download and read for free via Internet Archive. Recommendations gladly accepted. Happy reading ya'll!

(Please note this will ONLY contain books found through Internet Archive and no other sources, I don't want to run into possible mistakes and copyright headaches.)

Update: This list will also include books you can borrow through Open Library, a part of Internet Archive.
