Yes, Edenbrooke by Julianne Donaldson is a clean book.

Marianne Daventry escapes a dull season in Bath for her twin sister's invitation to Edenbrooke, a grand country estate — and arrives to find a highwayman on the road behind her and an infuriating, impossible-to-ignore gentleman waiting at the house. The novel that launched Shadow Mountain's Proper Romance line, an imprint built around romance written without explicit content.
