Sing, O Muse [Percy Jackson]

Thalia panted and glanced over her shoulder to shoot Clarion a glare more menacing than the monster's, "Can you do anything? Pull out your sword!"
"I, uh - I'm really more of a writer and musician than-" She glanced at the lion and shuddered as it growled and clawed at the air, but retreated from the shield each time Thalia thrust it forward with a menacing sneer. Clarion wasn't made for battle, she knew that - they all knew that - so why had she crashed their quest?
Thalia wanted to smack the girl with her shield. "Then start singing a damn calming song or write a story in which it goes away!"

or, in which Clarion strives to rival Homer and to write an epic to last the millennia, guest starring herself.
