The Book of Love - Kathleen McGowan

Once there was a gospel written in Christ's own hand: a treasure of almost unimaginable magnitude, referred to by the Cathars of medieval France as The Book of Love...
Fresh from her successful search for the long-hidden scrolls written by Mary Magdelene, journalist Maureen Pascal now finds herself on the trail of the legendary lost gospel known as the Book of Love. But just as there were those who would stop at nothing to seize and suppress the Book of Love seven centuries ago, so there are those today who are equally determined that its radical message should never be revealed. In a race across Italy and France, new dangers await Maureen and her lover Sinclair as they begin to uncover secrets and shine new light on the hidden corners of Christianity.
Combining expert research with dazzling plot twists, The Book of Love is sure to thrill readers as they follow Maureen's search for clues through some of the world's greatest art, architecture and history, until a potentially fatal encounter reveals the Book of Love to her -- and to us.
