Two camps, One Prophecy

Evil has awakened and only two demigods can stop it. The only problem? One is from Camp Half-Blood and the other is from Camp Jupiter.

Rachel has revealed the next Great Prophecy and Chiron, along with the two roman and greek demigods are not to keen about going on this quest, but with the fate of the world in their hands, they have no choice.

The new prophecy:

Two half bloods will take a stand
To one crystal, evil will rise
Earth, water and sky will be searched
Both will fight but one will fall
A camps bond will make it through all

Their quest, to find each of the crystals that represent the Olympians. But they have to find one before Kronos has the chance to rise again fully.

The two demigods absolutely hate each other though, they are from opposite sides of the gods, but they are the only half bloods from both camps worthy of this quest. Will they be able to get along, will something happen between the both of them, or will they end up tearing each other apart?
