Throttlebound

An electric fusion of biker romance, werewolf legend, and biomech suspense

When federal biotech investigator Sera Vantrel follows a trail of stolen research into the Nevada desert, she expects a routine bust-not a ghost town alive with impossible sound.
Ashgrave Flats is nothing but salt, silence, and the low, thrumming heartbeat of something buried far beneath the crust.

That pulse belongs to the Saltspire-a dormant biomech organism older than any myth, capable of twisting metal and flesh into living weapons.
And the only people reckless enough to live above it are the Steel Vow MC: a pack of Ruinborn werewolves whose bones gleam with living alloy and whose motorcycles howl like thunder.

Among them is Kade "Deadturn" Rix, the club's lethal enforcer.
Storm-gray eyes. Tattoos veined with shifting metal. A wolf that refuses to be tamed.
Kade can't scent a mate bond in Sera... yet every time she draws near, the unstable beast inside him steadies.
Her heartbeat cuts through the static like a perfect frequency-and that makes her either a miracle or a weapon.

As salt storms warp the sky and the Saltspire begins to wake, Sera is forced into a fragile alliance with the very predator who should terrify her.
Together they must uncover the truth behind her father's classified experiments, out-race biomech creatures that rise screaming from the flats, and ride the edge of a resonance powerful enough to shatter worlds.

But danger isn't the only vibration between them.
Every midnight ride through the silvered desert pulls Sera deeper into Kade's gravity-
and every brush of his alloy-laced skin sparks a need she's never known.
He is heat and engine growl. She is logic and law.
To survive the Saltspire's awakening, they'll have to choose trust over fear and desire over duty... even if it means surrendering to a bond that defies science itself.
