Takes place after the Deathly Hallows and the Blood of Olympus Percy Jackson thought he could finally live a normal life. He was going to fail high school, be the captain of the swim team, spend a whole, normal year with Annabeth. Yup, not gonna happen. Harry Potter has to redo his seventh year at Hogwarts. At least he gets to be with his best friends. Then some new kid shows up and he can't help but be a little jealous. He was the grandson of Voldemort and the girls were just falling at his feet. Even Ginny and Hermione were swayed by this boy. He was a death eater, and Harry could prove it. Luckily for him, the Triwizard Tournament was right around the corner. If the death eater was chosen, it'd be fun to watch him fail. Warning : Ron/Hermione and Harry/Ginny did not happen yet. Second Warning : Sirius, Snape, and Dumbledore are still alive. Just a disclaimer for the whole book : All rights go to Rick Riordan and J. K. Rowling Cover courtesy of @thatgirlariadne

The Giant war is over and Percy Jackson is spent. Finally there's a chance he can be with Annabeth for a while and he eagerly awaits the summer they have planned together. But when Hecate shows up and sends Percy on a new quest, it could be the by far stupidest thing he has ever done. He must be the new teacher at Hogwarts. Harry Potter has been attacked by the Ministry and Dementors. If that wasn't enough he now has a new teacher. But he is like, a 17 year-old kid. Who looks a lot like him. It's Harry's 5th year and he is now a nutter to the wizarding world. So when he sees the kid show up at Number 12 Grimmauld Place, he starts thinking he might actually be mental. The new kid turns out to be a teacher. The teacher of DADA. But Umbridge is still there- as the High Inquisitor. It seems she watches the new teacher-Professor Jackson- a lot more than the others. Something is off about him. And the Golden Trio always tries to find out what.

We won the war against Gaea, I was overjoyed. That is, until I saw blonde curls stained red. A month after Annebeth died the camp was attacked, causing a big secret Chiron kept from me to surface.

Takes place after the Emperor of Nihon-Ja and the Blood of Olympus Percy Jackson is your everyday Greek Hero. Slaying monsters, roaming the underworld, defeating Titan Lords and Earth Primordials, surviving Tartarus. You know, the usual. His heroism has put him at the top of every monster's kill list. His loyalty makes him a great friend to all. His achievements bring awe into the eyes of his allies. He's been through everything anyone could think of. But even he couldn't see what was coming next. Will Treaty. The Ranger who was apprenticed to the legendary Halt. The apprentice who forged a treaty between the notorious Skandians and Araluen. He is famous across the country, and even elsewhere, places like Arrida and Nihon-Ja. An air of mystery wraps itself around the youth like the mottled cloak of a Ranger. He and his friends have fought for the good of their country and others. Never have they had to fight for the sake of another time. Grimsdell Wood, the forest surrounding Castle Macindaw and the home of Malcolm and his people, has been said to be haunted for years. Little under a year ago, people started disappearing. They would wander into the forest and never be seen again. Rumor had it that Malkallam would snatch them in the dark. Only a select few know that the forest is not actually haunted, but a figure of tricks and illusions. Still, villagers would disappear. Not even Malcolm knows to where. Always the Ranger, Will, along with Halt, Princess Cassandra, Horace, and Alyss investigate. Only to disappear as well. How will Araluen survive without its saviors? The better question : What will happen when our favorite Medieval Legend and Greek Hero collide in an epic race against time? Author's Note : Please pretend that Will is around the same age as Percy, even though he should be much older.
