Elizabeth Knox ~ Daylight

'Brian 'Bad' Phelan is an expert climber and caver and, while on vacation on the French-Italian border, he helps bring a body out of a rocky, wave-swept cove. Curiously, the dead woman bears striking similarities to a young woman he met years ago, shortly before she disappeared in a flooded French cave. Haunted by the strange connection, Bad is compelled to investigate. While following a series of increasingly eerie leads, Bad learns the story of the Blessed Martine Raimondi, a World War II resistance heroine and martyred nun. He also meets Eve Moskelute, the beautiful widow of a celebrated French artist; Daniel Octave, a Canadian Jesuit who investigates miracles; and, most surprisingly, Dawn Moskelute, Eve's twin sister, who just may be a vampire. Daylight is set in one of the most beautiful regions on earth, with delights such as the unspoilt beauty of the Cinque Terre and the antiquities of Avignon, yet much of the action takes place in a world of caves and secret passages, of hidden cloisters and the rooms behind doors in the vaulted tunnels of medieval streets. '
