In 1865, Duncan regains consciousness on Bidston Moss, a freezing desolate marshland on the Wirral peninsula. His mind has been rebooted; all his memories erased. But something in the procedure has not gone to plan; there is blood all over his shirt - not his own - and he feels an irresistible passion for a woman he has no recollection of, her face somehow etched into his mind. In a typical overreaction, Lucie heads to present day Lisbon after receiving a weird and disturbing voicemail from her friend Emma who is on a physics internship for the summer at the prestigious Bisset Science Institute. But Lucie finds no answers in Lisbon as unwittingly she is sucked ever deeper into a chaotic and terrifying mystery. These two disparate storylines woven into the fabric of space and time converge inescapably as the implications of Duncan's original surfacing collide head on with Lucie's ever more desperate attempts to uncover what has become of her friend.
