Vampires own the night in Regency London.

After centuries of delivering impartial justice as the Vampire King's Blade, Anton Grazki's heart is encased in ice.

Lady Sybil Lofstrom, descended from a race of Fae thought to be extinct, is a ladies' chaperone. She never mentions the monsters she sees roaming the streets at night, fearing accusations of madness. When she and Anton meet face to face in Vauxhall's Dark Walk, he realizes her power to destroy his race, yet she seems to trust him.

Will Anton do his duty and eliminate the threat to his race? Or will he follow the urgings of a heart he believes died long ago and risk everything?
