Wendy Martin w/ Miranda Mundt, CASTLE SWIMMER: VOL 3

Graphic novelist Wendy Martin returns for Castle Swimmer: Volume 3 in which Kappa and Siren’s adventurous journey into the vast ocean begins. She is joined by fellow graphic novelist Miranda Mundt.

After leaving Siren to recover from his wounds in the shark castle, Kappa heads out into the big wide ocean once more. Minutes into his newfound freedom, another prophecy intervenes, pulling him towards a giant demigod crab scuttling along the ocean floor. As Kappa tries to figure out why he is drawn towards this crab, he comes across three magic-wielding octopi with tragic pasts and uncovers more about his greater purpose as the Beacon.

When Siren finally leaves the shark castle a month later, Kappa is long gone. Alone in the greater ocean, which he's only ever heard about, Siren quickly realizes that he's unequipped to fend for himself. After his supplies are stolen by thieves, Siren finds himself by luck in the company of a young fish and his mother and joins them on their travels. As they teach him to fight and tough it out in the wild, Siren begins searching for a cure to his curse.

This beautiful graphic novel collects episodes 42-65 of Webtoon's Castle Swimmer and includes three new mini-episodes, plus exclusive bonus content.
