Yes, usually. I've made my way through many a middling book that's 'fine' but certainly not great, yet persevered until the end.
There is only a small handful of books in my time that I have utterly, utterly failed to get into and have therefore put down and given up.
The only one in recent years is The Thursday Murder Club (😮 I know, right).
I have no idea why. People rave about it, it's supposed to be excellent. I got about a fifth of the way through and just couldn't bear it and realised I didn't even care if the characters lived or died 😂
My mum is appalled at me and encourages me at least once a week to start it and try again 🤣
