One treasure. One voyage. Two rivals. In the spring of 1901, Amelia Harlow boards a revolutionary steampunk airship for its first cross-ocean flight. Her fellow passengers trade worried whispers about a paroled murderess traveling with them, but Amelia doesn't fear her. She didn't come for the unique experience or abundant amenities. The woman owns a singular map Amelia could sell for a fortune if she can steal it. Running into Darius Shank poses the biggest challenge. The thieving lover who once cost Amelia everything eyes the same target. Rekindling their close but vindictive teamwork, Amelia must appease Darius while staying one step ahead of him. She doesn't plan to leave without the map or expect a new, forbidden romance to complicate her mission. The map's profit would do more than set Amelia back on her feet, but eagerness could draw the wrong attention in such tight quarters. To keep Darius from hurting her innocent acquaintances or herself, Amelia plots her moves wisely. She has six days to secure a brilliant future or lose the chance of a lifetime.
