In the book Story Genius by Lisa Cron we read:
Even if she's only six, she already has a worldview that, like most of us, she's never even questioned—why should she? As far as she can see it's "just the way things are." Boy, is she in for a rude awakening. [...]
(Yes, punctuation's been double-checked)
My question, of course, pertains to 'is she in'. How does this inversion find its explanation?
I guess it falls in what's taken as an informal register, but still I don't know if it's the matter of putting more stress on specific words or something else (intonation...?)
I would appreciate more examples like this from your smart linguistic heads and a word of explanation!
