Heart of Iron

McMaster’s second paranormal set in a steampunk alternate London (after Kiss of Steel) expands an intriguing universe. Lena Todd escaped the slums and made her way into the vampire high society called the Echelon. The devious debutante has a secret: she’s a spy for the humanists, a revolutionary group seeking to make humans socially equal to the “blue bloods” who rule the city. When Lena gets in over her head, only one man can save her: verwulf Will Carver, known as the Beast. As Will battles his lust for Lena, she struggles with her own feelings for him while fending off advances from a devious blue-blood duke. Even returning readers will have trouble keeping track of everything that’s going on, but they’ll love the sexy, action-packed narrative. Agent: Jessica Faust, BookEnds. (May 7)
