When you reach a point in a project where you really need to know if a story makes sense to someone who lives outside your head, to whom do you normally turn?
I've got a few friends who are often willing to give feedback, but all to often reading a novel isn't on their priority list.
One of my friends, as an example, has a copy of every book I've ever written, and has never read any of them. He got a few pages into the children's book while riding an airport shuttle, but fell asleep (not because the book was boring; he's narcoleptic).
So what do you do to get that all-important outsider's view?
