If there’s no particular need for that, I’d use a normal header block 
and \fromproperty.

Try this:

%%%%%%%%%%%%%%
\version "2.19.22"

\paper {
  bookTitleMarkup = \markup {
    \fontsize #15 \wordwrap-field #'header:title
  }
}

\book {
  \header {
    title = "Many many words may result in a title that is too long for 
one line"
  }
  \relative c' { c d e f }
}
%%%%%%%%%%%%%%%

I don’t know how to center-align the wrapped lines, though… Anyone?

Best, Simon
