I'm reading from first to last page and I'm a slow reader - I would never manage 100 books a year as most members here do, you all have my deepest respect for this - and I'm a friend of really thick books. If I like a book I hope it will never end!
My "weakness" is that I'm a "parallel" reader, too, there are mostly 4-5 books I'm reading simultaneously, not included the books I have to read for work and study. I've been trying for a long time to stop this behaviour, but then, when I'm down to one or two books there surely will come another most interesting one my way. Can't help it.
