Can one gentle Highland soldier woo Victorian London's most scandalous lady assassin, or will they both be destroyed in the attempt?

New York Times bestselling author Gail Carriger presents a stand-alone romance novella set in her popular steampunk universe full of manners, spies, and dainty sandwiches.

Lady Preshea Villentia, the Mourning Star, has four dead husbands and a nasty reputation. Fortunately, she looks fabulous in black. What society doesn't know is that all her husbands were marked for death by Preshea's employer. And Preshea has one final assignment.

It was supposed to be easy, a house party with minimal bloodshed. Preshea hadn't anticipated Captain Gavin Ruthven - massive, Scottish, quietly irresistible, and... working for the enemy. In a battle of wits, Preshea may risk her own heart - a terrifying prospect, as she never knew she had one.
