When the Burying Ground goes down in neutral waters, it sends the delegations from two warring nations--and the peace treaty they were about to sign--to the bottom of the ocean. The only survivors are a pair of teen girls: Cora, daughter of a Duran newspaper man, and Vivienne, lady's maid to an Ariminthian princess. Neither has known a time when war between their two countries did not rage, but now they must learn to trust each other if they are to find sustenance, avoid dangerous pirates, and have any hope of rescue from the remote island they washed up on. However, in the midst of a conflict steeped in fierce national identity, propaganda, disinformation, and radicalization, finding a common path forward seems nearly impossible, for both Cora and Vivienne and their respective countries. But when the teens' politically charged rescue seems likely to extend the war, Cora and Vivienne realize they do have a shared purpose: peace. If only it isn't too late.
