" As our ship tumbled, free-falling through the eye of a saltwater cyclone, the nine giant maidens spiraled around us, weaving in and out of the tempest so they appeared to drown over and over again. Their faces contorted in anger and glee.
Their long hair lashed us with icy spray. Each time they emerged, they wailed and shrieked, but it wasn’t just random noise. Their screams had a tonal quality, like a chorus of whale songs played through heavy feedback. I even caught snippets of lyrics: boiling mead...wave daughters...death for you! It reminded me of the first time Halfborn Gunderson played Norwegian black metal for me.
After a few bars, it dawned on me...Oh, wait. That’s supposed to be music! "

― Rick Riordan , The Ship of the Dead (Magnus Chase and the Gods of Asgard, #3)
