What a Spinster Wants by Rebecca Connolly

Lady Edith Leveson has lived her young widowhood in shadows and secrets, not even revealing the truth to family or friends. That, it seems, is no longer an option, and she must act quickly to avoid being ruined entirely and forevermore. A handsome but reserved rescuer comes to her aid just in time, and their paths begin to entwine more than either of them expected.
Graham Hastings, Lord Radcliffe, is no hero. He isn’t brave, bold, or in any way noble, yet the striking Lady Edith seems determined to paint him so. One dance with her, and he seems unable to avoid finding her in need wherever he goes. The more involved he becomes, the more his heart begins to open, and he finds himself more than willing to become a hero. Hers.
