* Annabeth's love for Percy: Throughout the book, Annabeth shows unwavering support for Percy, even when he doubts himself. She trusts him implicitly, even when others don't, and is always willing to fight alongside him. This is most evident in the scene where she defends him against Luke (page 250).
* Percy's love for his mother: Despite the challenges he faces, Percy deeply loves his mother, Sally, and is determined to protect her. He even risks his own life to save her from Hades (page 298). He constantly thinks about her and misses her (page 46).
* Grover's dedication to Percy: As Percy's satyr guardian, Grover demonstrates unconditional loyalty and care for him. He puts himself in danger repeatedly to protect Percy and is always by his side. He shows deep concern for Percy’s well-being (page 77) and encourages him even when he feels defeated (page 240).
These examples, while not using the exact term "unconditional love," clearly show characters prioritizing the well-being of those they care for, even when it means putting themselves in harm's way. This is a core theme throughout the book and illustrates the strength of these relationships.
It's important to remember that literature often reveals emotions through actions and behaviors rather than explicit statements. By analyzing these examples and the overall narrative, we can glean a deeper understanding of the powerful bonds of love and loyalty present in "The Lightning Thief."
