When Dashing Met Danger by Shana Galen

Lucia Dashing, youngest daughter of Viscount Brigham, has been in love with the Earl of Selbourne since her sister married his half-brother five years before. At that time, Alex didn’t look at her twice. Now, when a family matter brings them together again, Lucia doesn’t think it’s just her imagination that sparks fly between them.

Alex can’t believe the beauty Lucia has grown into. He also can’t believe what a headstrong, impulsive creature she’s become. Or how much he likes those traits in her. She’s not like other women, and that makes her dangerous. As a secret agent for the Crown, Alex is equipped to deal with danger, but she may prove deadly. But when he’s assigned to find her missing twin brother, he can’t escape the clever beauty.

Lucia knows there’s more to her brother’s disappearance than she’s been told, and she has a plan to find him. She just need to convince Alex to let her help. Despite Alex’s refusal to involve Lucia, the two are caught up in a world of treachery and deception. They must rely on each other to survive, and the closer they become, the more dangerous their attraction grows.
