Within Kronos’s ranks, Luke Castellan is struggling. He’s no longer certain of his path, and as tensions rise, he begins a quiet rebellion against everything he once believed....Luke has disappeared and things have calmed down. But a few months into the school year, Percy begins receiving mysterious notes from an unknown demigod. After several exchanges, the sender is revealed to be none other than Luke Castellan. They continue writing to each other, checking in from afar… and perhaps that’s when things begin to change.
