He and his band of pirates are bound by vow to patrol through Threshold, the magical sea in between realms, keeping the portals to other worlds safe. When he rescues Evelyn, he doesn’t expect to be attracted to the unflappably brassy pickpocket. The longer he spends in her presence, the more he begins to question if his heart is the next thing she’ll steal.
