Villains Are Destined to Die: vol. 7

Just when Penelope and Callisto think they're safe, a torrential wave plunges them deep into the ocean! All Penelope can focus on is getting out alive, so...how did she end up with Callisto's lips on hers?! With Eckles's affection meter reaching 99%, though, the duke's daughter can't afford to dwell on the other love interests. Her coming-of-age ceremony is swiftly approaching, which means the end of Hard Mode follows right behind. One measly percentage point away from finally escaping the game - can Penelope make it in time...?!
