The London Season is ushered in with a thrilling flurry of invitations, gowns, and parties. But despite her status as belle of the ball, lovely socialite Emma Drake simply cannot fathom becoming entangled with any gentleman of her acquaintance. For in truth, since childhood her heart has belonged to Captain Sidney Fletcher, a man of the sea—and her brother’s best friend. Emma knows that Sidney’s directive to free the Spanish city of Cadiz from French occupation will be dangerous, but when word arrives of his capture, she is frantic. Determined to aid her brother in Sidney’s rescue, she hides aboard his ship and sets a course to Spain. But the realities of war are a far cry from the drawing rooms of London, and Emma finds the man she loves a mere shadow of his former self. When a series of events leaves them trapped together behind enemy lines, Emma and Sidney must embark on a journey fraught with danger—from a bloody hunt for Spanish treasure to the battlefields of war-torn Spain, new threats lurk around every turn. As their flight becomes increasingly perilous, Sidney and Emma must trust each other with their lives—but can they trust the other with their heart?
