Blood of Olympus by Rick Riordan
There's no more time! The battle to prevent Gaea awakening is now! But the questing demigods have to first prevent all out war between the Greeks and Romans and unite to prevent the monsters and Titans from destroying the Earth as they know it.
The gods themselves can be no help (they're all suffering from Multiple personality disorder - both their Greek and Roman sides are warring) so the demigods each must complete their mission to prevent the catastrophe. Nico and Reyna are tasked with return the Athena Parthenos to Camp Half-Blood which should stop the infighting between Greek and Roman.
The rest on the Argo II must rescue Percy and Annabeth (they always seem to be in trouble) and prevent the spilling of their blood on Olympus.
This was an action finale to a fun and enjoyable series! My only disappointment was the ending seemed unsettled - not a cliffhanger - as if the author was leaving an opening for another?
