Quitting a Book

Do you ever quit reading books you just can't get into or don't like? I'm currently 100 pages into a book and although the writing is well done and I'm interested in the setting, I simply don't care what happens next. Usually I keep plodding through to make sure I don't miss out if it gets better. I can think of two specific books that I quit because the writing was trash. (I'm thinking of you, self-published romance author hawking your book in Costco!) And for some reason I was never excited to pick up Hotel on the Corner of Bitter and Sweet or whatever that book was called. Even though everyone else raved about it. Maybe I finished it, I don't remember. I just remember wishing I was reading something I actually liked and what terrible feeling it was to have to read something you don't want to. Hold on, I'm going to check my Goodreads... Nope, never finished it. Well good for me. That's exactly what I'm going to do with the book ...
