Jack Frost and Perseus Jackson come together at LAST! The two teams must combined to save the world against Kronos and Pitch Black. Will they do it? Or will they tear each other apart? And will Jack Frost and Leo Valdez, the first firer user in forever, get along? Or will there be a war between fire, and ice? Where they still have the matter of fire and ice, the demigods have been betrayed once again. And once again, it is some one close. Someone inside. Someone has been telling Pitch and Kronos their every move. Who do you think it is? Is it one of the 5? Or is it someone who has nothing to gain, nothing to earn, but is doing it anyway?

They try to make their way back to camp, but old grudges are still being held. Enemies have not forgotten. And when one of them comes back for revenge, Leo and Calypso are hurled into one of their most dangerous challenges yet. In the meantime, the rest of the seven are frantic. They beat Gaea, but their victory came with too high a price. But six months after the battle, they begin getting signs and visions of their lost hero. Could Leo really be back?

This is a Caleo fanfic. I hope you enjoy

It's been three weeks since Percy died and came back to life. 2 weeks since he left camp to go find answers. He knew his friends were lying to him; they were keeping secrets. So, he went out on his own to find out what went down when he was gone. Along the way, Percy stumbles into the lives of the two famous Winchester brothers, Sam and Dean. The brothers don't know what to make of the demigod, but soon enough, they are fighting side by side with him. But will the Winchesters and the Seven, with the help from the one and only Jack Frost, be able to save Percy from his one true enemy: himself? Join Percy, Sam, Dean and Jason and the rest of the gang as they battle a greater foe in which no one will ever expect. Book 2 of the Rise of the Demigods series. (Go read Book 1 if you haven't already!!!)

The Seven are back in this installment of The Rise of the Demigods. In this story, the Seven have just finished fighting the evil Earth Mother, Gaea. But when a new threat arises, the Seven are going to have to team up with the famous children legends- the Guardians. Join the the demigods and the Guardians as they battle their worst enemy- their nightmares.

Guess what?! Another Heroes of Olympus and Harry Potter crossover. I felt obligated by the fandoms to write this. Anyways, it's your basic The seven go back in time in 1998, after the wizarding war is over. Their mission is to go to Hogwarts and befriend the wizards as allies, particularly the three wizards that their world calls heroes, the golden trio. Attention!!!!!!!!! Harry Potter + friends will NOT be smug and full of it! I hate when the demigods go and op everything. The seven will NOT all be in the same Hogwarts house because technically they are all very brave, so I will have the sorting hat look past all that to the reasons why they are brave. So Percy may or may not be in Hufflepuff! Final notes: I write basically all of this on my phone, so please excuse the spelling errors :) Also, I own none of the characters all rights reserved to Rick Riordan and JK Rowling.

(I kept alive: Fred, Snape, and Dumbledore) The seven, Nico, the Stolls, and Thalia, and Clarisse are sent to Hogwarts after the major wars. The wizards know what they are, and both sides are seeing how wizards and demigods interact, so they can possibly be allies. Someone is causing trouble trying to keep then apart, but who?

The eight demigods (Percy, Annabeth, Frank, Hazel, Jason, Piper, Leo, and Nico) embark on a quest to the wizarding world as they are assigned to go to Hogwarts, undercover. There they meet the trio as well as many of the other wizards and witches. What will happen when these two worlds meet?

In the wizarding world, Harry, Ron and Hermione are invited back for their seventh year at Hogwarts. The war has left a huge impact on everyone, and the three are hoping to be able to relax and enjoy their final year at school. But honestly, fate just has to- [better not finish that sentence. After all, the Three Fates can get very touchy...] At Camp Half-Blood and Camp Jupiter, another quest has been issued, and much to the complaints of everyone, the Seven, Thalia and Nico are sent to Hogwarts. They soon find out that there is no time to enjoy themselves, though, because something primordial, something ancient and powerful is stirring, and it is stirring awake... "Nine half-bloods roam the sorcerers' land." "Child of the dead halts second chance." "Join the fates of worlds beyond," "Who unite to battle the bane of bonds."
