Grandson of Voldemort

Percy Jackson, 2 time saver of Olympus, thought that he was finally going to lead a normal life. Well, relatively normal for a demigod 😜. But , when dark cloaked figures attack he's in for another wild ride!
It had been 7 years since Harry had defeated Voldemort, he became an aurror and had a child named James with Ginny. But when he finds out Voldemort is back and
has a grandchild it flips his whole world upside down.
