His Beauty by Caroline Lee

She needs his library. He needs his solitude. A Highland blizzard needs them together.

Bonnie Oliphant needs one thing to save her struggling publishing house: the legendary Oliphant art collection, guarded by the most reclusive man in the Highlands. She’s willing to brave even the wrath of the scarred outsider known as the Beast of the Oliphants, if it will salvage her dream.

Lyon did not agree to a houseguest. He didn’t agree to laughter echoing through his castle, or someone reading history aloud in his library, or a woman who looks at his scars like they’re the least interesting thing about him. He especially didn’t agree to a blizzard that makes it impossible to send her home.

Snowed in together at crumbling Oliphant Castle, Bonnie dismantles Lyon’s defenses one laughing, infuriating, magnificent act at a time — and Lyon discovers, to his considerable alarm, that a beast can learn new tricks.
