I've heard that there is some big prophecy that you don't find out until the fifth book. Is that Chiron's prophecy he got from The Oracle that's about Percy and Annabeth and all that? Also, is the fifth book the last book? NO SPOILERS PLEASE! I only just finished the first book. I just want to know if that is the prophecy or not. Thanks!

a halfbloold of the eldest gods
shall reach sixteen against all odds
and see the world in endless sleep
The hero's soul cursed blade shall reap
a single choice shall end his days
olympus to preserve or raze

The prophecy is that a son of one of the "Big three" will decide the fate of the olympians at the age of sixteen. they tell you in the second book.
