In the rain-lashed hills of County Kerry, Ireland, the silence is a predatory lie. Beneath the gorse and ancient stone circles, a necrotic, high-frequency hum vibrates in the marrow of the earth, for the veil between the mortal world and the Otherworld is no longer just thinning; it is a jagged, festering wound bleeding obsidian shadows into the mist.

One world is turning to glass. Four souls are the only anchor.

Siobhan O'Shea has spent her life trying to drown out the Sight, the terrifying sapphire clarity that reveals the monsters hiding in plain sight. But when Cianán, a brooding Fae prince draped in ancient exile, crashes into her reality, her world of books and hearth-fires incinerates. His touch is a volcanic jolt, a carnal intrusion of heat that defies the sub-zero frost of the Bone-Throne. Marked by the Morrígan's wrath, Cianán is the anchor to a destiny written in kyanite-light, and Siobhan is the only needle capable of sewing reality back together before the Samhain Eclipse burns it all to ash.

While Siobhan navigates the glittering treachery of the Fae courts, her brother, Liam, commits the ultimate metabolic sin. To save his sister, the ink-stained scholar binds his soul to Finnegan, a chaotic, predatory Púca whose silver tongue is as dangerous as his stallion's teeth. Their bond is a visceral, bone-deep pact that blurs the line between man and beast, scholar and ledger. In a world where magic is a parasite and every spell costs a piece of the soul, Liam must decide if he is willing to lose his humanity to the very ink he uses to write their survival.

In the first book of The Ogham's Toll series, the boundaries of love, identity, and biology will be pushed to the breaking point. Because in the end, to be human is to be breakable, and to be breakable is the only way to be truly touched.

The eclipse is coming. The ink is drying. The Toll must be paid.
