A Lady in Name by Elizabeth Bailey

On discovering she is the illegitimate daughter of a peer of the realm, Lucy Graydene, bereft and grieving, sets out to confront Lord Pennington with the result of his misdeeds. She finds instead his autocratic heir, Stefan Ankerville, and is dragged willy-nilly into the new earl’s unconventional family. Lucy is driven to battle for her independence while she struggles against the venom of the half-sister she never knew she had.

When the secrets of Lucy’s past begin to unravel, she is reluctantly obliged to rely on Stefan’s help. Can Lucy overcome a dangerous attraction to the earl, with whom an alliance is impossible? Or is there a faint hope of happiness in the hidden truth of her origins?
