Every Action Has a Price. Every Secret Has a Consequence.

The struggle for the security of London’s hidden underbelly didn’t end at Golden Square. In this high-stakes continuation of the LineFolk of London saga, Hannah Chadwick finds that being an apprentice to the legendary Wayworthy legacy is less about ancient books and more about surviving the "Edge".

While Axton Flynn struggles to master the centuries of inherited memories now locked in his mind, the sanctuary of the clynic is under threat. A rival healer is becoming empowered in the shadows of the Circle Line, and patients are disappearing into a world of secrets that even the Master’s memories can’t fully explain.

As a rhythmic, spectral tapping begins to haunt Hannah—a sound no one else can hear—she is drawn toward the dark history of Cockpit Steps. Something is energising the city’s phantasms, fuelled by a resurgence of Victorian-era cruelty.

From the electrified tracks of the Underground to the blood-stained sawdust of an illegal gambling circuit, Hannah must navigate a world where LineFolk are once again being treated as sport. With the fierce werecat Mia at her side, Hannah discovers that her own evolving power may be the only thing capable of tipping the scales.

In a city built on top of monsters, the most dangerous thing you can do is care.
