Fallon is the daughter of a proud Celtic king and the younger sister of the legendary fighter Sorcha. When Fallon was just a child, Sorcha was killed by the armies of Julius Caesar. On the eve of her seventeenth birthday, Fallon is excited to follow in her sister's footsteps and earn her place in her father's war band. She never gets the chance. Fallon is captured and sold to an elite training school for female gladiators—owned by none other than Julius Caesar himself. In a cruel twist of fate, the man who destroyed Fallon's family might be her only hope of survival. Now, Fallon must overcome vicious rivalries, deadly fights in and out of the arena, and perhaps the most dangerous threat of all: her irresistible feelings for Cai, a young Roman soldier and her sworn enemy.
