The only place to hide could be behind the truth. No one can lie to Louisa Cobb. It’s her gift. Her curse. Magic her stepfather has no compunction about using to gain the upper hand in business. But when Parnaby Cobb presents her with her latest mark, she realizes he’s testing her loyalty. Her target is Patrick O’Connell, an Irish tinkerer and scoundrel who stole a kiss—and her heart—years ago. Should she betray her stepfather to set Patrick free, she’ll be cut off without a penny to her name. Patrick knows exactly he’s been captured, why he’s struggling to lie into Louisa’s sky-blue eyes. He’s invented a device to stabilize and direct the mysterious Eros Element. If he fails to recreate it for Cobb, his closest friends’ happiness will be at risk. Back in Boston, as Patrick stalls for time and Louisa uncovers secrets of her tragic past, the two of them engage in a treacherous dance on the edge of love and danger. Where one wrong step could condemn them both to everlasting heartache—and unleash an unimaginably powerful force that could destroy their world.
