In the ancient Mediterranean-inspired kingdoms of Xanthos and Phalesia, war is coming whether the rulers admit it or not. Dion, overlooked second son of Xanthos's king, can see the threat in the strange warships and disappearing ships; Chloe, daughter of Phalesia's First Consul, refuses to be a pawn in anyone's game. When Chloe is taken hostage, Dion must seek the most powerful allies available—the eldren, a race of shapeshifters living in the Wilds, whose own survival is entangled with the coming war.

Dion is a reflective, principled young man whose 'overlooked second son' status has freed him from the rigid expectations of kingship—making him better suited to lead than anyone anticipated. His arc from uncertain prince to battle-tested king is matched by Chloe's own growth from determined survivor to a woman who reshapes the very idea of what power can look like.

Across four books, The Shifting Tides traces the escalating clash of civilizations as a dragon-commanding tyrant, Palemon, threatens to destroy everything Dion and Chloe have built. The series moves from political intrigue and personal discovery in book one through naval warfare, magical arms races, and the cost of power across the following volumes. The finale asks what peace truly costs and how different peoples can survive together—drawing on the author's deep research into ancient history, naval tactics, and mythology.
