Laura und das Orakel der Silbernen Sphinx

Laura Leander's father is still held captive by the Black Prince Borboron, and the only way to free him is to recover the legendary sword Hellenglanz before Borboron does. The search takes Laura, riding her horse Sturmwind, deep into the mysterious Fatumgebirge — territory guarded by a giant Silver Sphinx that will only grant passage to those who answer its oracle's riddle correctly. No one has managed it yet, and a wrong answer means death.

Third book in Peter Freund's Laura Leander series, following thirteen-year-old Laura — guardian of light since her thirteenth birthday — and her continuing fight against Borboron.
