After picking the wrong pocket, street rat Lumi finds herself entangled in the dangerous world of notorious pirate lord, Rook. Lumi's past is a mystery she can't seem to unravel. When Rook discovers she can read the ancient dialect on his treasure map-a language long extinct-he decides to keep her close. He buys her freedom, but there's a catch: first, she must join him on his treasure hunt. Before handing her over to Rook, Lumi's master makes one final promise-Lumi's stolen memories will be returned if she brings back Rook's head. Caught between a chance to reclaim her past and a growing attraction to Rook, Lumi faces an impossible choice: claim the memories she's desperate for, or follow her heart into uncharted waters. In a world where betrayal is as common as the tides, Lumi must decide if the past is worth the price, or if the future is worth the risk.
