About AJ Carter

AJ Carter writes psychological thrillers that dig beneath the surface – where the quietest moments hide the darkest secrets. Based in the UK, he crafts stories of tension, obsession, and the fragile edges of the human mind, exploring what happens when ordinary people are pushed far past their limits.

Fueled by curiosity, caffeine, and an unshakable interest in why people do the things they swear they never would, AJ creates worlds that are as unsettling as they are addictive. His work is known for sharp realism and gripping, high-velocity suspense – stories that pull you in from the first page and don’t let go.

When he isn’t writing, AJ’s usually watching films that mess with your head, losing time to story-driven games, or travelling in search of inspiration – and the kind of places that make you double-check the locks at night.
