Sixteen-year-old Amara has always believed she knows her family. She lives a comfortable life with her wealthy parents in Lagos, surrounded by everything a girl her age could want. But for as long as she can remember, Amara has been haunted by the same nightmare: a terrified woman crying in a dark room while her father drags her behind a locked door. Everyone tells Amara it's nothing more than a childhood nightmare. Then, one ordinary afternoon, Amara discovers a hidden door inside her father's wardrobe. Behind it is a room that should not exist. And inside that room is a woman who has been imprisoned for years. A woman Amara has never met. A woman whose face she has seen countless times in her dreams. The woman's name is Lydia, and she claims she was once the family's maid. She also claims that Amara's entire childhood is built on a lie. As Amara secretly returns to the room, Lydia slowly reveals a horrifying story of abuse, betrayal and captivity. She tells Amara that Victor, the man Amara has called her father all her life, destroyed her life and took away something she could never replace. Her child. The more Amara investigates, the more pieces of her childhood begin to fall apart. Old memories suddenly make sense. Questions she never thought to ask become impossible to ignore. And the people she trusted most begin behaving like strangers. But Lydia's story is only the beginning. Amara soon discovers that her family has been hiding more than one secret. Victor's respectable image conceals a dangerous criminal world, while Esther—the woman Amara has always called her mother—may know far more about Lydia's imprisonment than she admits. As Amara gets closer to the truth, she realizes that exposing her parents could destroy the life she has always known. But keeping silent could leave Lydia trapped forever. And when the people responsible realize that Amara knows too much, she becomes their biggest threat. Because the woman behind the door isn't the only secret her family has buried. And the truth about who Amara really is could change everything.
