All the Spells and Whistles — Ava Stone

When Miss Poppy Elstone discovers she's a witch, she doesn't have the first clue how to use her magic or control her powers. She does know that she must keep her abilities a secret from the world or risk all kinds of danger. She now wakes every morning, having dreamt about a stranger at a crossroads until one night when the dream and the stranger in question become all too real. A shell of his former self, Captain Alec Galbraith returned from the Napoleonic battlefields, determined to make his own fortune and forge his own destiny in spite of his lost magic. When his path collides with Poppy's one darkened night, she sparks something in his soul he thought was lost. Can Alec teach Poppy how to use her powers? Or will his dark past stand in the way?
