Blood.

Lets analyze shall we?

We demigods have been given the name of the last (but hopefully not last)
installment of the Heroes of Olympus series; Blood of Olympus which will be released
in 2014. (ehhgard)

What do you other demigods supposed the name means? In the last few books,
we have been given hints that the blood of some of our brothers and sisters
will taint a place for life. (IDK about HoH cause i haven't read it you, no hate
ya'll, we're family.)

So I wonder if there is more to the name than bloodshed in the war for Olympus?

What do you guys think???
