[Tex/LaTex] Insert text between title and author

titles

I'm writing a book review, and I'm trying to follow the style template, after which the bibliographic details about the book I'm reviewing go in between the title (which is simply 'Review') and my author details. I'm customizing \maktetitle with titling (the package documentation is not an easy read, so I might be doing that wrongly).

What can I do to add something between the title and my author details?

\documentclass{article}
\usepackage{titling}
    \pretitle{\begin{flushleft}\LARGE\textbf}
    \posttitle{\vskip .25ex\hrule\par\end{flushleft}}
    \preauthor{\begin{flushleft}\large}
    \postauthor{\par\end{flushleft}}
    \predate{\begin{flushleft}}
    \postdate{\par\end{flushleft}}
\begin{document}

\title{Review}
% The bibliographic details about the book I'm reviewing go between the title and my author details.
\author{\textbf{Paul McCartney}\\ University of Liverpool}
\date{\today}
\maketitle
\noindent Here my review begins
\end{document}

Best Answer

Personalize at will:

\documentclass{article}
\usepackage{titling}
\pretitle{\begin{flushleft}\LARGE\textbf}
\posttitle{\vskip .25ex\hrule\end{flushleft}}
\preauthor{\begin{flushleft}\large}
\postauthor{\end{flushleft}}
\predate{\begin{flushleft}}
\postdate{\end{flushleft}}
\renewcommand\maketitlehookb{%
  \begin{quote}
  \thebookdata
  \end{quote}
  }
\newcommand{\thebookdata}{Missing book data} % default value
\newcommand{\bookdata}[2]{%
  \renewcommand\thebookdata{{\large{#1}\par}#2}%
}
\begin{document}

\title{Review}
\author{\textbf{Paul McCartney}\\ University of Liverpool}
\date{\today}

\bookdata{Book title}{by A. Uthor}

\maketitle
\noindent Here my review begins
\end{document}
