The Ambiguous Enigma of the Hunted Lady by Emma Linfield

Trust is a dangerous game…
Thrown into a world she never chose, Leah Benson was raised to be the perfect thief.
When her own partners turn against her, Leah must run for her life. With an ingrained dislike for nobility, she never thought she’d end up under the wing of the Duke of Worthington.
Kenneth Wilson, Duke of Worthington, saves a young woman from being assaulted by unsavory individuals. However, he doesn’t anticipate the secrets her presence alone will expose about his very own past or the feelings she will evoke within him.
In a race to discover the one that wants them dead, there is something important that Leah and Kenneth don’t realize: someone’s set a trap for them and they are walking right into it…
