well, i really wanted to vote for PORTUGAL but lucky you, i started last year keeping a list of the books i read so now i can answer (before, my answer would have been "i really have no idea"). it turns out, in 2008, i read 57 books, however of those, about 5 were started but not finished in 2008 (i sometimes read more than one at a time, and if a book is not the right one for my mood i will leave it for later).
this year, so far i've read 18 books, however one of them was Monsieur Lecoq by Emile Gaboriau ; almost 800 pages long, so it should count for at least 3 !
it took me nearly a month. but normally it seems i average about one book per week.
to be honest, i was surprised ; i would not have thought i read so many books, but i suppose i should have known, since when i used to get them at the library, i would usually take 5 at a time (the maximum) and at the end of the 3 week loan period, usually have to renew 2 of those...
and no, these are not 10 pages long books, since you asked.
(but most of them are not 800 pages either !)
