“Are you sure this is safe?” Joel looked back at his brother. “Safe as jumping,” Randy smirked, referring to their frequent weekend trips to the surface where they challenged the gravity of the satellite. Debbie and William Ryder call the massive asteroid, Demeter their home. All is quiet, or is it? What looks to be a large PerSian invasion fleet is on the edge of Demeter space and the Saggitarian armada that is supposed to defend Demeter leaves port. This leaves Ryder and his friends in a struggle to find a way to defend Demeter with the scraps left behind by the alien fleet. Meanwhile a secret lurks in the inner tunnels of Demeter that could either save or destroy the planet, and explain the attempts to kill the Ryder siblings. Will Ryder and his rag tag team of friends be able to find the answers and resources in time to save Demeter from complete Destruction? … another delightful installment. The intensity and intricacies of the plot continue to build as this series continues. Many of the characters are really coming more and more into their own as they face situations where they have to make decisions that they know will impact not only their own lives, but the lives of others… Fair warning: each book gets harder and harder to put down.
