A mediocre fantasy series starter sends a group of children on an adventure that will probably have them saving the world in the third volume. Robin lives on the magical Lost Isle that floats between The Real World and The Uncertain World. One day he wants to be a knight, but now he’s a puny victim of bullies, disgraced by his Renouncer father who left The Lost Isle forever. Robin shows unprecedented magical ability, and becomes apprentice to the sorcerer Quadehar. When monsters from The Uncertain World attack Robin’s schoolyard tormentors, prodigal Robin’s magic is enough to rescue only one of them. Robin learns that he is the monsters’ intended target, and decides to rescue the bully Agatha. His four best friends accompany him on his mission to The Uncertain World, where Robin’s bungled spell scatters them across the land. After adventures, they regroup, prepared for the trilogy’s center. Insubstantial. (Fiction. 8-10)
