'The slightly OCD princess was doing just fine, thanks.
'Then she got thrown to her death.
'That might have put a crimp in things.
'Princess Eloise, Future Ruler and Heir to the Western Lands and All That Really Matters, swallowed back her "habits" and went after her missing twin sister.
'She found her.
'Awesome!
'And then they both got chucked into the mysterious, magical, deadly Purple Haze.
'Less awesome!
'While her champion (a nervous, yammering chipmunk) and her guard (the human incarnation of rectitude) rot in prison and her two horses desperately try to find some way to help, Eloise and her sister go deeper into the Purple Haze to discover the source of the inner tug they both feel.'
