Hecate's sacred polecat has gone missing. Hera suspects that wizards and witches, a race that has been hidden from all demigods, are behind it. She plans to wage a war against them. However, Hecate fears the complete annihilation of her own race that she created, knowing that they are weak when compared to the powerful demigods. She concludes that the only way to reunite the two races and bring peace to the worlds, is to send some demigods and wizards on a quest together. So she chooses four demigods and throws them into a world mysterious and completely foreign to them. Thanks to @Chocolov3r for the amazing cover ~ Featured on the official Percy Jackson reading list for @Fanfic ~ [this is a PJO/HP crossover and all characters belong to their respective owners-Rick Riordan and J. K.Rowling]
