Falon Macvail is barely fourteen years old when her family is forced to flee their home in Scotland, leaving behind everything she's ever known in the hands of greedy landowners. As their beloved country struggles through a time of great civil unrest and class upheaval, Falon and her family travel to a raw wilderness called Texas. Far from the threat of their murderous evictors, the Macvail family must carve out a new life amidst the dangers of a new frontier. When the rumblings of a war with Mexico begin and an implacable enemy invades from the south, ravaging the countryside and leaving a trail of death and destruction behind them, Falon must take a stand once more and find the courage to protect those in her care from the enemy crouching on her doorstep.
