Caged Birds Fight, Too

Greece has been conquered by the Romans. Faith in the gods (both Greek and Roman) is dwendling, and the gods themselves have a great threat coming their way. Lyra is a demigod. Daughter of Apollo the god of poetry, prophecy, archery, medicine, music, and the sun. Apollo sent his daughter a message telling her to gather up fellow demigods and come to the aid of the gods. Before she was able to begin her quest, she was captured by Roman soldiers and thrown into the coliseum. If she can survive one hundred life or death battles, she can win her freedom. But Lyra doesn't have that kind of time. She's got to gather allies and escape the coliseum before its too late, and Olympus is destroyed.
