I am searching for the title of a book about some plague or virus slowly eliminating the human race while there is a "spirit" world above (beside...anyway, linked to it), where deads remain for a while, as long as they are remembered by at least someone on Earth (they don't completely disappear until they disappear from the souvenirs of everyone on Earth). The last surviver is a woman working up at the North Pole.... can't say more. Does it ring a bell?
Thanks in advance.
S.B.
