Dillon, Winston, and Lourdes survived the disaster that killed their companions Michael and Tory. As Winston struggles to locate Dillon, now a prisoner, Lourdes succumbs first to her personal demons and then to the influence of the soul-eating Vectors, powerful beings intent on conquering Earth. To fight them, Dillon and Winston must accomplish the impossible: retrieve Michael, Tory, and the long-lost Deanna from death and win back the soul of Lourdes.
The book is at its best when focused on the thorny philosophical issues that the characters must confront--responsibility, connection, and forgiveness. At other times, particularly when the Star Shards approach their final confrontation, the story feels rushed. However, Shattered Sky is a satisfying conclusion to the trilogy. --Roz Genessee
