According to Luke is a thrilling romantic novel of secrecy, symbols, faith, and forbidden love. It takes the reader on a quest for an ancient truth so powerful it disturbs the Catholic Church: a truth so explosive it attracts violent separatists and demands a ransom of millions. Follow a chase that charges from Venice to Malta, and then to Ravenna: a chase that escalates to disaster in Damascus, until a solution is found in the Victorian countryside in Australia (author's website).
According to Luke features the secondary character Prof Bryn Awbrey, an expert in semiotics. He later appears in Dingli's 2013 novel The Hidden Auditorium ('Rosanne Dingli, The Hidden Auditorium And Why Writing Never Ends,' interview with Nick Wales 2013).
