The demigods rush to save Grover, who, as it turns out later, made an important discovery: he came across two demigods, whose origins are still unknown, but who possess great power...

In the entertaining and exciting third adventure of the series, Percy must face the most dangerous challenge: the eerie prophecy of the Titan's Curse...
