More Celebrity Half-Bloods?!

The One Direction half-blood gang has survived and grown closer through their fight with Kronos. He has been defeated by the newest member of the group and one of the most well known of the 1D girlfriends, Perrie. Everyone knows he will come back looking for revenge, so they need to be prepared. Luke is currently unconscious and being closely monitored to ensure that he really is Luke again. The half-bloods have to find a way to stop Kronos before he rises, but what happens when you add more celebrities finding out that they are children of the Olympians?
