[Book Two] Sequel to Skinny Dipping With a Mermaid. As if losing her father and friends during the Wizarding War didn't weigh heavy enough on the heart of Nixie Dover, to lose the love of her life to imprisonment in Azkaban due to false accusations completely shattered the woman. Turning to the sea for over twelve years, Nixie prepares to spend the rest of her life among the merfolk community and her mother, until she hears a rumour through the seaweed. Sirius Black has escaped Azkaban. Determined to see if the rumours are true, Nixie ventures to the land once more only to find him but to also find the world on the brink of the Second Wizarding War. Terrified of what could occur during the second fight against the Dark Lord and his followers, Nixie is hesitant to join the fight. That is until she hears of the newest secret weapon that can not only help them win the war but stop the Dark Lord once and for all. With unfinished business to attend to with an old Hogwarts "friend" Nixie prepares herself for the final fight.

Sirius Black told Harry that there were four Marauders. He told Harry that his best friends in school were James, Remus and Peter. He told Harry that there were three unregistered Animagi at the time he was at Hogwarts. He lied. There was another, only one other, who Sirius never mentioned. Perhaps because they had a falling out... perhaps because something happened to her. Rowan Mulciber is the missing Marauder, and this is her story.
