Castle Swimmer: Volume 4 by Wendy Martin delves deeper into the darkness of the ocean as Kappa and Siren uncover the harrowing truths of their own destinies in this thrilling fourth instalment of the hit Webtoon series.

Kappa and Siren continue their thrilling journeys beyond the kingdom walls. Accompanied by his new companions, Pim and Pagoon, Siren ventures into the shadowy ocean depths in search of a cure for his curse. Facing terrifying creatures that prey on their deepest fears and desires, the trio uncover more about Siren's prophecy and the darkness entwined with his fate.

Meanwhile, Kappa continues to battle the great demigod crab with the last of the Octalia people, learning to harness his magical powers and grow his strength. Despite being on separate missions, Kappa and Siren remain connected through their unwavering dedication to each other, even if it is just an inflicted hallucination.

Join Kappa and Siren as they bravely push forward into the unknown and face more mythical obstacles in this captivating continuation of the Castle Swimmer saga. This beautiful graphic novel collects episodes 66-86 of Webtoon's Castle Swimmer.

About the Author

Wendy Martin was born in the Midwest and grew up in Iowa. She spent her childhood raising animals, but she spent even more time drawing them. As she grew older, she dedicated more time to the arts and creating fantasy comics and stories, particularly ones that involved characters who were half human and half animal. After graduating high school, she worked as a waitress and continued making comics on the side until Castle Swimmer, a story about two mermen, was picked up by Ten Speed Graphic and allowed her to draw comics full time. Castle Swimmer is her first series.
