This takes place after Rise of the Guardians. You are reading in the perspective of Pitch Black's daughter. Instead of inheriting your father's powers, the Man in the Moon gifted you with the power to instill courage in mortal children and adults alike. The reader knows the first four Guardians already, but when she teams up with them to defeat Pitch, she is introduced to Jack Frost.

"Y/n?" The pale boy asked, you could see the hope in his eyes. "How do you know my first name? I've never told anyone my first name," You raise an eyebrow, "I only introduce myself as Cupid." His blue eyes turned from Hope to pure sadness, "You don't remember me?" You plop a piece of gum in your mouth. "I remember everyone I meet," you explain, "and yet I can't pinpoint any time where I've met you," you circle the boy. "But given that you know my first name, we've definitely met...which means one thing," you stop. "I met you before I died, didn't I?" (Idk the artist, sorry) #1 Jackxreader #5 snowflake
