The quote "Sounds like a plan worthy of Athena" from Rick Riordan's book "The Lightning Thief" reflects the character's admiration for a well-thought-out strategy. Athena, the Greek goddess of wisdom and warfare, is known for her intelligence and tactical acumen. This line suggests that the plan being discussed is not only clever but also strategic, echoing the traits associated with the goddess herself.

In the context of the story, such a remark emphasizes the importance of wisdom in overcoming challenges. The characters often find themselves in perilous situations where thoughtful planning is crucial. By likening the plan to Athena, the narrative highlights the value of intellect over brute force in the quest for success.
