Frostbound - The Dark Forgotten, #4

Every dog might have his day, but the hellhound guards the night . As a snowstorm locks down the city, more than the roads are getting iced. Someone's beheaded the wrong girl, and vampire-on-the-lam Talia Rostova thinks it was meant to be her. Now she's the prime suspect in her own botched murder-and the prisoner of her smoking-hot neighbor. Lore is a hellhound, bred to serve and protect, so he's not freeing Talia until he's sure that she's the prey and not the hunter.
You'd think a beautiful woman in his bedroom would be a good thing, but trouble-prone Talia has run afoul of someone more sinister than your average lunatic killer. An ancient Undead is wreaking vengeance on the city-and on her-and Lore will have to go far beyond a stake to put him back in his grave . Second edition. Previously published in 2011 by Signet Eclipse
