I actually really like Emma Stone, but being a redhead (or at least often-dyed-red-head) with a crazy gleam in her eye, she'd do a good job as the psychotically deadly Krystal who joins Thanatos in book 2 (Underworld's Daughter).
Anne Hathaway is just beautiful with fair skin and dark wavy hair. Love her look. Inspiration for a girl who originally thought that fair skin, brown hair, and brown eyes was boring instead of beautiful.
