The Watchers (The Angelus Trilogy)

Beneath Lausanne Cathedral, in Switzerland, there is a secret buried before time began, something unknown to angels and men, until now...

Marc Rochat watches over the city at night from the belfry of the cathedral. He lives in a world of shadows and "beforetimes" and imaginary beings.
Katherine Taylor, call girl and daydreamer, is about to discover that her real-life fairy tale is too good to be true.
Jay Harper, private detective, wakes up in a crummy hotel room with no memory. When the telephone rings and he's offered a job, he knows he has no choice but to accept.

Three lives, one purpose: save what's left of paradise before all hell breaks loose.
