Some secrets can last for centuries.

Marcus Weaving is a retired psychology lecturer and therapist. Not a man to sit around, he volunteers at his local university. Years of clinical practice are put to the test when he receives a mischievous text from somebody called L.

Intrigued and unnerved, Marcus goes to the address provided and is welcomed by a beautiful blonde woman named Lily. Their story goes way back to his tumultuous youth when he had to flee from his abusive mother and other demons skulking around.

Timing for a romantic reunion could not be any worse. Marcus is about to become a grandfather and he has ongoing issues with his estranged, drug addicted son.

Why has Lily shown up after all of this time? And, why hasn't she aged a day?
