Forgotten City Books in Order

Forgotten City opens on a strong image, a ruined world split by a wall. Thirty years after civilization fell apart, humans scrape by in fear and scarcity while a massive barrier keeps the so-called monsters on the other side. Everyone is taught the same thing. The wall protects humanity. The creatures beyond it are the danger. Stay away, obey the rules, and survive.

Naturally, the series starts by breaking that lie.

The first book follows a heroine who slips through the wall and thinks she understands the risks. She does not. Once night falls and she is trapped in the old city, the monsters come out, and the story quickly turns from survival thriller to dark paranormal romance. But the larger hook is not just attraction between human and monster. It is the growing realization that the official story about the city, the wall, and the creatures inside may be backwards.

That bigger mystery is what gives the series its shape. The second book widens the lens by moving to a heroine with status and scientific ambition on the human side of the divide, and her story pushes harder into the truth behind the monsters' existence. By the time the larger arc comes into focus, the series is no longer just asking whether humans and monsters can trust each other. It is asking who created this world, who benefits from the fear, and what was done in the name of keeping order.

So the setting matters a lot. The forgotten city is not just a cool backdrop full of shadows and ruined streets. It is a prison, a lie, and a record of what happened when power decided some lives were expendable. Outside the wall, humans live in slums and hunger. Inside it, the monsters carry their own scars, rules, and hierarchies. The line between those two worlds is where the tension lives.

The tone is dark and romantic, but it also leans into dystopian atmosphere. Expect survival pressure, hidden histories, experiments, and the slow peeling back of propaganda. These books are linked, and even though different couples help tell the story, they work best when read in order because the truth behind the city keeps unfolding piece by piece.

If you like monster romance with an actual larger plot underneath it, Forgotten City is very much built for that. The creatures are part of the draw, but the wall, and the reason it exists, is what really keeps the series moving.
