How to Be a Scottish Mistress — Adrienne Basso

She's his in every way. . .
When newly widowed Lady Fiona Libourg flees to Scotland in need of protection, Lord Gavin McLendon is powerless to refuse the British beauty. Especially when she offers herself in exchange. Now the brooding Scottish warrior can think of nothing else but ravishing his delectable new mistress, even though he's dutybound to marry another. . .

But one. . .

Fiona is shocked when Gavin accepts her scandalous offer -- and fretful at the thought that he will discover how little she knows of seduction. But when Gavin proves to be a skilled and achingly sensuous teacher, Fiona doesn't want their passionate arrangement to end. Now she can't help but wonder just what it would take to go from Scottish mistress. . .to Scottish wife.
