She can save her husband. But only by destroying the world where their daughter is still alive. Eighteen months ago, grief therapist Elena Vasquez buried her seven-year-old daughter. The drunk driver. The intersection. The phone call that split her life into before and after. Now she's losing her husband too. Marcus hasn't left her—not exactly. But every night he straps on a DreamBridge headset and vanishes into a parallel world where the accident never happened. Where Sofia is alive, laughing, learning to read chapter books. Where he can hold his little girl again. He always comes back. But lately, he comes back different. When Elena discovers the horrifying truth—that DreamBridge doesn't just let users visit parallel lives, it slowly trades their consciousness with their alternate selves—she realizes Marcus isn't escaping into fantasy. He's being erased. Piece by piece, memory by memory, her husband is becoming someone else. And the man replacing him? He's waking up in a world where his daughter is dead and his wife is a stranger. To save Marcus, Elena must infiltrate the corporation behind DreamBridge and destroy the technology at its source. But the people who built it have secrets of their own—and reasons to keep the bridges open that Elena never imagined. How far would you go to save someone you love? And what happens when the answer is the same for everyone? Some doors, once opened, can never be closed. — Parallel Dark is a mind-bending thriller about grief, identity, and the seductive lie of escape. Perfect for fans of Blake Crouch's Dark Matter, Matt Haig's The Midnight Library, and anyone who's ever wondered what they'd sacrifice to have one more day with someone they lost.
