Answer to Fairday's Riddle: Changing Waves~

Excellent guessing, Riddlers. We'll be riding a changing wave next week. Tune in Monday to find out how the answer ties into the story. See you all around the book block. ~ F

Curved and constant with peaks and dips; ravishing froth, silky slips. Back forth in ebbing ways; cast in motion for displays. Up, down, here and there, flowing almost everywhere. Forceful, smooth, swirling, high— describing styles in the eye.  

What am I referring to? Answer: Waves!
