The Blood of Olympus (Fan-Fic)

"Seven half-bloods shall answer the call
To storm or fire the world must fall
An oath to keep with a final breath
And foes bear arms to the doors of death"
These words may seem insignificant to a mortal, but to these half-bloods it means the world. Literally. A group of the seven most powerful demigods of their age must join forces to fight against Gaea's army and stop her from rising on the Feast of Spes.
Can they do it?
What will happen when the daughter of Athena cannot think of a plan?

What will happen when the daughter of Pluto is at death's door yet again?
What will happen when the great son of Mars burns up?
What will happen when the mighty son of Jupiter falls?
What will happen when the daughter of Aphrodite is no longer in control?
