I reckoned the approach with the flag the most beginner-friendly because you 
don't have to think too hard about the corner-cases, namely

>>> book_title("")
''

When I use the "process first item before the loop" approach I usually end 
up with a helper generator

def _words(words, small_words={w.title(): w for w in small_words}):
    yield next(words)
    for word in words:
        yield small_words[word] if word in small_words else word

def book_title(s):
    return " ".join(_words(iter(s.title().split())))

and the nagging thought that I'm making it more complex than need be.
