"I know what you are, Percy Jackson, Half-Blood Prince of the Sea." --- Percy, Annabeth, Nico and Will are thrown back into the Wizarding world for a second year, but what they find there is not what they expected. Magic isn't fun and games anymore, not when one of their lives are on the line. A familiar face resurfaces, a dark plot is hatched, and relationships are put to the test. Are the demigods fit to take on this new year at Hogwarts? And will they be able to keep their secret from friends and foe alike? --- {Book 1: Babysitting Hogwarts - Completed} {Book 3: To Thwart The Darkness - Completed} Disclaimer: I don't own Percy Jackson or Harry Potter, credits go to J.K Rowling and Rick Riordan Disclaimer: I do not support J.K Rowling or her opinions.
