The castle of the demigods (PJO+HP crossover)

This is a Percy Jackson and Harry Potter crossover. This is after the wizarding war when the Hogwarts School is letting them have another year to make up for all the war business that happened last year derailing them from their studies. Percy Jackson and the crew are sent out to go look around at some of the strange attacks that have been going on in diagon ally, and with Harry's weird dreams of a man in control of monsters, what are they to do? In a new mysterious quest compelling them to work together, even if right now another battle is the last thing either of them want right now. Maybe one day they'll get a break but it aint today. (maturity on the level of use of drugs and alcohol)
