The O'Keefe Family Collection - Books 1-3: Exploding, Escaping, Exhaling
Tuesday Embers, Mary E. Twomey

To break away from her overbearing brothers, Irish girl Fallyn O’Keefe opens a bakery to show them she can do it on her own. She thinks her biggest problem will be defending her storefront from the violence of the rival family, who would much rather see her chased back into the east end of the city with the rest of the brawling O’Keefes.
When Vince, the older, terrifying head from the enemy family shows up with flowers instead of his gun, Fallyn worries the fighting between her family and his will escalate from fists to firearms.
