After her husband casts her out for being fat and penniless, Celia Wrenford answers a notice to become a mother for a little boy—and steps into the world of Sir Merrick Ashbourne, the feared Steam King. What starts as a contract marriage changes as her warmth softens Bram’s pain and stirs Merrick’s guarded heart. When her arrogant ex returns to mock her, Merrick stands beside her, declares her his wife, and destroys the man’s business. A marriage on paper becomes a love neither expected.
