When I returned to the joys of reading a few years ago, a couple of books I bought were written in present tense. They sat on my shelf for a few months as I delved into other books written in the more familiar and comfortable past tense. But when I eventually got round to reading one of them, I found that after a few chapters my brain had been reprogrammed to recognise present tense as normal. It didn't bother me any more and I simply enjoyed the stories.
Since then I've branched out and read books written with multiple viewpoints (first, third, different characters), as well as books written in either tense. CITIZEN VINCE by Jess Walters even switches to second person for a few paragraphs every so often and it actually enhanced my enjoyment of the book.
The novel I'm writing now is mostly in present tense, with semi-dream sequences in past tense. My reasoning here is that I want it clear that the dreams are set in the past.
But I'm wondering, how do all of you feel about techniques like this, switching tense and characters? Is it gimmicky, does it add to your enjoyment of the novel, or does it all come down to how good the writer is and how well the techniques are handled?
I'm especially interested in the views of readers on this, because of my novel, but also just plain old curiosity.
