Saved By the Belle by Shana Galen

After successfully completing his first mission as a Royal Saboteur, Hew Arundel is in London on holiday. But his entertainments are cut short when he’s attacked in the street. When he wakes, he’s not only in pain but in an unfamiliar setting. He might be half-delirious, but he’s not imagining the smart-mouthed woman charged with his care. Belle isn’t a skilled nurse, but she’s smart and fearless, and Hew finds those two qualities irresistible. And dangerous. Hew’s heart has been damaged before, and he swore never again to allow a woman to breach his defenses. Belle doesn’t seem interested in him anyway…until they share a forbidden kiss.
Belle Howard was born with a specialized palate. She knows exquisite tea by scent and taste and has used that talent to turn her family’s business, Howard’s Teas & Treats, into one of the premiere tea shops in London. When circumstances force Belle and her father to care for an injured man, they aren’t sure the man will survive. They certainly don’t expect his would-be assassins to wreak havoc on their lives. Now Belle is caught up in a dangerous mission and even more treacherous is the way Hew Arundel makes Belle feel whenever he looks at her. But Belle has learned not to trust men. If only she could remember that when Hew takes her in his arms.
