I read The 7 1/2 Deaths of Evelyn Hardcastle, and take enjoyed it. Read another book, then started reading Devil and the Dark Water by the same author. I got about 25% through and just decided to drop it for something else. I’m not an avid reader so i never know if I should stay committed or not.
You have no obligation to finish a book. There are too many good books out there to waste time on one you don’t like!
(Also you’re completely right, 7 1/2 Deaths… was such a brilliant book but his follow up had that second album problem. Hopefully the third will be great)
