But when she arrives, she is horrified to find that the CRU have taken more victims. Emily has no choice but to expose herself, Pegasus, Joel and their close Olympian friends including Lorin, to the biggest danger they've ever faced, as they delve deeper into the CRU and make an astonishing discovery about its origins. A discovery that means Emily will be forced to return to Titus to face Saturn, before an unstoppable force of evil is unleashed on the unsuspecting worlds.
