Sir Jasper Lynch is TheNighthawk. As an outcast blueblood, a rogue, it was his idea to take other rogues and give them a purpose and a place in the extremely hierarchical society of London. But since the bombing a month earlier, Lynch's main job is to capture Mercury per the Prince Consort's orders. It's Mercury's head or his. But the woman is an intriguing creature whose mere presence creates more conflicts than Sir Jasper has ever experienced. He's always been the cold, analytical, driven man but Mercury brings out his baser instincts. But, then, so does his new secretary, Rosalind Marberry, who delights in tormenting him in small flirtatious ways, thus creating new levels of conflict.
But the love interest between Lynch and Rosa isn't the only plot line. Rosa is searching for her younger brother, Jeremy, who helped deliver the bomb that set into motion the Prince Consort's ultimatum to Lynch. There's a minor line about the humanists wanting to get some basic rights with the Echelon as well. Plus there's a line that pertains to the mechs in the humanist movement who also have wants and needs.
Bec McMaster's Steampunk series has become one of my favorites. The men are pure alphas - strong and confident, intense and sexy even if they're just standing still. They never lose sight of their goals…and, in My Lady Quicksilver, that creates some amusing scenes with Rosa/Mercury becoming jealous of herself and with Lynch condemning himself for not being true to Rosa. Or Mercury. I particularly liked the Strip Chess playing scene. That's not something you find every day. Of course, the chess got left behind for a game of Twenty Questions but the result - the Strip - created a steamy level 'Reach for your ice water' .
All in all, this is a terrific book, worthy of multiple reads. Treat yourself to a copy.
