There's loads I might quote, but one of my favourite opening lines in spec fic is from Mary Gentle's
Ash: A Secret History: "It was her scars that made her beautiful."
A couple of non-spec favourites -
One Hundred Years of Solitude by Gabriel Garcia Marquez - "Many years later, as he faced the firing squad, Colonel Aureliano Buendia was to remember that distant afternoon when his father took him to discover ice."
Or
The Crow Road by Iain Banks - "It was the day my grandmother exploded."
Then again, of course, there's always the opening to Edward Bulwer Lytton's 1830 novel
Paul Clifford - "It was a dark and stormy night..."
