I like it when authors take advantage of chapter breaks to add to the story by using meaningful titles or something other than numbers to set the mood or hint at what's coming. For example in The Book Thief, Markus Zusak uses sections and pulls phrases and words out to pique the reader's interest.

What I can't stand are faux-hooks at the end of a chapter that turn out to be quickly resolved at the start of the next chapter For example, She heard a terrifying howl. (end chapter)
(next chapter) She'd stepped on her cat's tail... blah blah

If the story is interesting I'll keep reading it without the Hardy Boys style cliffhangers at the end of each chapter.
