This is the second book in the Castleton Series. Allie, Jen, and their engineer visit Roman Carthage on a research mission. They are captured by bandits who sell them into slavery, scattering the three time travelers around the Roman Empire. The Time Institute realizes it has lost a crew, but has no idea where or when. They need a rescue team that is courageous and innovative. The CT 9225's team of young Fixers fit the bill. Mike Castleton, Patrick Weaver, and Nick Pope, now in the 7th grade at Atlantic Academy, accept the mission. They must retrace the lost crew's steps, discover what happened, and bring their fellow time travelers home. By the time they arrive will their friends be alive or dead? Can they be saved without changing time and setting off Chaos? Do their friends want to be saved? You'll discover once again that time travel messes with your mind and with your heart.
