Snowbound intrigue, second-chance love, and a stolen cipher threaten England and two wounded hearts. A blizzard seals Kellynch Hall on Twelfth Night, trapping Anne Elliot with Captain Wentworth, the naval hero she once loved and lost, and a stolen Admiralty cipher that could invite Napoleon's invasion. Rumors coil through candlelit corridors, masked dancers hide traitors, and Anne alone can read the silent signals Wentworth sends across the ballroom. Forced together in frost-rimmed passageways, they have one night to unmask the thief before betrayal and rekindled passion bring both the nation and their hearts crashing to ruin. The cipher's disappearance places every guest under suspicion, but none more than Wentworth, whose recent victories at sea have made him both a hero and a target. To shield him, Anne must confront her scheming cousin Mr. Elliot, who will expose her father's crushing debts unless she agrees to marry him and relinquish Wentworth forever. As snow deepens and tempers flare, secret letters, coded glances, and a perilous chase across the frozen park force Anne to decide whether duty to family outweighs loyalty to the man she never stopped loving. One mis-stepped waltz could cost England its defences. And Anne her last chance at love.
