House of Cards
A covenant broken. A hell unleashed...
New York City's only legal counsel to the fabled Old Races, Margrit Knight is levelheaded in all matters extraordinary. But when she's summoned to negotiate a peace treaty among rival factions, her own mortal world threatens to fall apart.
Margrit's been in hot water before, but reentering the underworld brings a new set of problems. And a new set of friends and enemies, including a ruthless vampire mobster, a dragonlord who won't take no for an answer, a band of subversive selkies... oh, and Alban Korund, the sexy gargoyle who got her into this mess – and whose granite-strong touch still haunts her every fantasy...
