This has echoes of the Pied Piper but only to a lesser extent. The children who follow the piper are escaping the destruction of their settlement by bandits. Not really my favourite of hers it's still an interesting read and well worth the time. It's told from a first person point of view by the eldest of the children who doesn't sound all that young, but then again lives on a colony planet as a first wave of settlement so may have more responsibilities settled on his shoulders earlier and if it's written by him later, the more adult attitude may be excused as filtered by this.
Not one of her best but does display a lot of her typical themes, children taking responsibility, questing, etc.
