Yesternight

What if the universe had a memory-and you were the infection it was trying to forget?
Dr. Elias Thorne, a brilliant quantum physicist based in Jeddah, can travel through time. Not with a machine of gears and wires, and not through a portal. He travels by riding the Yesternight-a Category Five electromagnetic storm that tears the fabric of reality itself.
When his brother Tariq is murdered during one of these catastrophic storms, Elias makes the ultimate sacrifice: he jumps back to save him. But he soon discovers a terrifying truth. Every intervention doesn't just change the timeline; it fractures it, birthing darker, more twisted worlds. Worse still, the universe has an immune system. When a paradox is created, it generates shadowy, featureless entities known as Echoes-the universe's antibodies, sent to hunt and erase the anomaly.
As Elias and Tariq navigate collapsing realities-from a dead, irradiated Earth to a gleaming dystopian empire ruled by a monstrous alternate version of Tariq himself-Elias's own memories begin to erode. The true cost of time travel isn't just the world around him; it is his own mind. Guided by Elara, a mysterious woman bound to him across every timeline by shared destiny and loyalty, Elias must face an impossible choice.
To save everything, he must lose himself. To fix the timeline, he must break his will. To survive Yesternight, he must become the wound.
Yesternight is a mind-bending, deeply psychological sci-fi thriller that explores the devastating cost of power, the unbreakable bonds of brotherhood, and the profound weight of memory.
