When a mother picks up her son's toy laser gun and flicks it on, she expects nothing but a harmless flash of light. Instead, the beam reveals something impossible-a shimmering portal hidden in the ordinary shadows of her kitchen.

Stepping through, she stumbles into a secret world controlled by the Gatekeepers, unseen rulers who shape human perception and dictate what is real. Their power is absolute, their influence unquestioned. But now, she knows they exist.

Some truths are meant to stay hidden. Some doors, once opened, can never be closed.

As she pieces together the terrifying reality behind the Gatekeepers' control, she realizes knowledge is both a gift and a curse. The deeper she digs, the more dangerous it becomes. They do not tolerate those who question them.

With reality itself at stake, she faces an impossible choice: stay silent and live in ignorance-or fight to expose the small truths that could one day set humanity free.

Perfect for fans of Blake Crouch, Philip K. Dick, and Black Mirror, Through the Shutter is a mind-bending sci-fi thriller that will leave you questioning everything you thought was real.
