It's a life of quiet, predictable bliss. Until the house next door is sold.When the vibrant, captivating Orla moves in, Aoife's world is tilted on its axis. It begins with a flicker of movement in the dead of night: her husband, sneaking through their new neighbor's garden. Aoife's investigation starts with the simple, agonizing suspicion of an affair. But the clues she uncovers-an antique key to a lock she's never seen, a secret painting with a violent, familiar style-don't add up.The truth isn't in the present, but buried in the past. A fatal car crash on a dark, rain-slicked road fifteen years ago. A ghost of a girl who never came home.As Aoife digs deeper, she realizes the affair is just a clever lie, a performance designed to distract her from a far more sinister truth. A truth that connects her husband, her new neighbor, and even her own mother in a conspiracy of silence and blood money. The perfect life was a perfect lie. But in a garden built on graves, discovering the real serpent is more dangerous than living the lie.
