The fourth book in Joey Weiser's Eisner Award-nominated series is now in paperback! It's all-out war between Mer and Atlantis! At least that's what Mermin's father, King Merus, declares after Pete is taken by Atlanteans. And that's not all-Mermin will be fighting side-by-side with his father, so it's time for some intense training! Meanwhile, deep in the underwater Kingdom of Atlantis, Pete is sent to an orphanage since his family cannot be located. His stories of Mer attract the attention of another child, who offers to introduce Pete to her "friends"-whom he never expected to see in Atlantis!
