Jerusalem, 1099 AD, was the central focus of the First Crusade, the holy war between Christian Crusaders and the Saracens. Passionately motivated by the sight of their Holy City, the Crusaders stop and wait for orders to assault the city's stone walls. In that moment of hesitation, wing-walkers Kate Phillips and Jen Fillmore are pulled from twenty-first century Earth World and hurled into the land of Domar in Bigna World. The two find their lives caught in a world of medieval knights and scaly beasts, far from their high tech world. Brought to Domar to find a cure for the Bás plague spreading throughout Domar, Kate and Jen are plunged into the deep, mystical chambers of Rapio, the sinister, dark Prince of Bigna. The fate of Jerusalem 1099 AD hangs on their actions in Domar. Blasting Trumpets, the second book in The Locket Chronicles, is a continuation of the life journey of two characters, Kate and Jen, who first appeared in The Morgan Chronicles, the first series by Carole Bailey.
