Percy Jackson grandson of Voldemort

Percy thinks he's off the hook after the giant war, but boy was he ever wrong! He had the perfect vacation to Europe all mapped out for Annabeth and him, he even flew there because he was granted to permission by Zeus (grudgingly)! But then they get chased by these guys named Death Eaters (what a silly name who would want eat Thanatos!)! And find out Percy is the grandson of the Death Eater's leader Moldy Shorts (It's actually Voldemort but whatever same thing)!It looks like Percy isn't done with war yet!
