It's not that I won't stop in the middle of a chapter, but I generally do read to the chapter break as well. Depends on the book of course - sometimes there are breaks within a chapter (like the Keith Richards' autobiography I'm reading now) that make sense to stop.

I usually read to the chapter, but my biggest problem is authors who leave you hanging at the end of the chapter. If I am reading, it is usually at night....and I keep reading until I get to a part where I can go to sleep. But then there is the problem that once I am halfway through the chapter, I keep reading. Next thing you know I am at another cliff-hanger. This trend continues and before I know it, it is 3 a.m. and I am done with the book!

I read until something forces me to close the book. It's nice if I'm at a convenient break point, but that doesn't always happen.

I also try to finish a chapter before stopping. I always look to see how many pages are in the next chapter before I start reading it! I even do this with my Nook!

It depends on the length of the chapter. For James Patterson books, for instance, where the chapters are often just a page or two long, it's easy to read to the end of the chapter. But for others where chapters can run on for pages and pages and pages, I can stop anywhere, but I usually try to stop at the start of a paragraph on the top of the page.

I just put in my book mark and stop wherever I may be!
