Cataclysm: The Second Lost Legend of the Ruby Heart

Josias, grandson of Basilikos (the protagonist in RUBY HEART: The Legend Begins), must leave home after a cataclysmic event that has put his life - and the lives of others, in grave danger, should he stay. He takes with him his faithful servant, Haziel, his three cousins, Marzban, Arshad and Farbod - and the Ruby Heart.
In Daphne, north of Lake Huleh, just above the Sea of Galilee, he meets Jonathan (with and interesting connection) and his cousin, Eldad. They all go to Gamala where the second cataclysmic event begins to unfold, involving the capture of a leader of the Seditionists, plus two miraculous surgeries, the last of which spawns a possible romance.
Josias is introduced to Pliny the Elder, a true historical author of many books of immense historical value. Pliny hires him as his personal physician. Two months earlier Vespasian had given Pliny the command of the fleet based at Misenum on the west coast of Italia, at the base of Mount Somma - Vesuvius.
Josias arrives in Misenum near Pompeii, close to Mount Vesuvius in early summer, 79 A.D.
Historical Note: Mount Vesuvius erupted on August 24, 79 A.D.
The Ruby Heart:
The gemstone of the Legends is a ruby the size of a child's first. Its shape is similar to a human heart - hence the name. The Ruby Heart itself has no special powers. This is not sorcery, but somehow it connects with special God-given gifts in certain people. These gifts appear, so far, to be passed from generation to generation, sometimes even skipping a generation.
Cataclysm:
1. An event that brings significant changes.
