When last we saw British spy Tara Chace, she had just rained messy justice upon the extremists who bombed the London Underground and left the closest thing she had to a boyfriend dead on a Middle Eastern battlefield. Now she’s back, dragged out of retirement to liberate the son of the ailing Uzbekistani president before his power-mad sister kills him. While not as nail-bitingly prescient as A Gentleman’s Game, Greg Rucka’s sequel, Private Wars, is still a Swiss watch of a thriller: well-machined, precise, and inexorable. Oh, did I mention that Tara’s also got a baby girl? That just makes this secret agent one deadly hot mama.
