Jon Snow (character) [SEP] Introduction
In "A Clash of Kings" (1998), he joins a scouting party investigating the growing threat from the otherworldly "Others" beyond the Wall, and manages to infiltrate the wildlings. Jon learns of their plans to invade Westeros in "A Storm of Swords" (2000), and begins to fall in love with the fierce wildling woman Ygritte. He betrays them—and Ygritte—before they can attack, but the Night Watch's victory comes at a heavy price for Jon. Now the Lord Commander of the Watch, he appears briefly in 2005's "A Feast for Crows". Jon returns as a prominent character in "A Dance with Dragons" (2011), working to negotiate an alliance between the Night's Watch and the wildlings.
