One book that have been trying to finish since before Christmas is The Silent Patient by Alex Michaelides my DiL loved it. I am about 6 chapters in and not enjoying it, so have put it on my bookshelf to be read another time.
Don't bother with The Silent Patient GG it's rubbish! I plodded on, highly implausible tosh, just not worth the effort.
I read Lord of The Rings, and enjoyed it, in my younger days I was 18 or thereabouts, when I actually hauled it up to London to read on my daily commute, that was then, this is now and I couldn't be doing with any of that other world fantasy elf stuff these days. Even the film versions have me running for the hills. .
I confess to liking a couple of Thomas Hardy once too, they wouldn't appeal now, my son went through a phase of reading a lot of miserable books he actually enjoyed Tess of the D'Urbervilles a real tale of woe if ever there was one. 
I found Cloud Atlas heavy going, several people I knew thought it was sublime, although I thought it was a clever premise I can't say I enjoyed it.
Hated Lovely Bones, Time Travellers Wife, more lately Midnight Library and that awful and vastly overrated book by Richard Osman
The Leopard - Giuseppe di Lampedusa, a classic I believe, Rick Stein said it was absolutely one of his best books when he was promoting Sicily where it was set, certainly not one of mine.
My absolute worst book ever would be Lincoln in the Bardo which won all sorts of accolades including The Booker Prize, it wasn't that it didn't have a linear narrative, I found it positively unreadable.
However, I did enjoy some others' horrible books, Crawdads, The Goldfinch and Atonement (once I got about 50 pages in, it took a while from what I remember)
