All of a sudden she hears a crashing sound coming from downstairs.

She quickly gets up, listening carefully.

She turned to see a panther, silent, stealthy and the color of indigo night.

She gasped in amazement, yet fear, and grabbed the nearest object: a guitar.

Her hand brushed the strings and the thrum overpowered the low roar of the panther... or did it silence it?

"Well done, Giselle," a voice rumbled from all around.

Her voice caught up in her throat, and she could not utter a word.

"W-what exactly have I done well?" she stuttered after a moment, swallowing the lump in her throat.
