"How to Stop Time" has been on my book shelf for so long!! I really need to read it. I DNFed "The Midnight Library" at like page 60 because I just couldn't get into it. I seem to be the only person with that opinion though, so I'm going to give it a 2nd try.
I really love Matt Haig, but understand if his writing is not for everyone! I've seen more and more people discuss not loving the Midnight Library so you're definitely not alone in that!
