She's longed to glide above the waves like an albatross, watched the tide come in, dreamed of sailing along the glistening water under the moonlight while the whales sang their melancholy tunes.

It moves and writhes and wriggles like a beast, hiding below the surface and waiting to snap up unsuspecting victims.
