The Last Tideborn

A tide-hearing fisherman enters a contract marriage to save a restaurant from a monopoly.

On his divorce day, Ethan Cole pulls restaurant founder Margaret from the water, exposing his birthright as a Guardian of the Sea who hears ocean currents and underwater songs. He soon enters a practical marriage with ambitious Claire. Together they deploy his ancestral gift to locate massive fish schools and raid the forbidden Siren's Cove for rare catches, reversing the restaurant's collapse overnight. When a local fishing monopoly and his vengeful ex-wife attack, the couple counters by sharing techniques with independent fishermen and expanding the business along the entire East Coast.
