Her Canadian publisher's site lists her book as available in ebook with a list price of $32.99 Canadian. Perhaps email them and ask where the ebook is available?

EDIT: Just checked Shortcover's, since their Canadian (owned by Indigo) and they don't have it as a "Canadian" ebook either. You'd think if the Canadian pub put it out as an eBook a Canadian eBook retailer would have it.
