Katherine Bruno's passionate, unfiltered temper makes her the shrew of small-town Sweetheart, Texas. When she's drafted to help the mayor's wife run against her own husband, Katherine meets opposing big city political consultant Ryan Park. The good-looking, flirtatious campaign manager gets under her skin, but fraternizing with the enemy is off-limits.

Katherine must battle her lack of experience, campaign sabotage, and her growing feelings for Ryan as she strives to succeed. His unprejudiced acceptance of her strong-willed character beckons her heart, but his jaded rejection of God is an insurmountable barrier. Will Ryan return to his faith and stay with her in Sweetheart or leave when the election ends?
