The lighting thief

This is really your opinion. I like when they reach the river Styx and meet Charon, the ferryman. They pay Charon with stolen money from the water mattress store and reach the other side. Cerberus, the three headed dog, tells Grover that he's going to eat them soon, but Annabeth decides to distract Cerberus by playing fetch with him. She tosses a ball from the water mattress store and then after he retrieves it, tells him to sit and stay. They cross quickly past him, but alarms go off because their magical gear has been detected.
