This story takes place well after THE RETURN OF THE JEDI. Han and Leia's children (twins named Jacen and Jaina) are enrolled in Luke's Jedi Academy on the planet Yavin 4. One day when the twins were out exploring one of Lando's mining operations on another planet, a ship kidnapped them and took them to the new SHADOW ACADEMY. A place where they train dark jedi for the Empire. It's up to Luke and another of his students to rescue them. A good entertaining story. Aimed more at the young adult readers but still enjoyable for fans of the Star Wars books. This is book # 2 in the series.
