After a life changing and magical year at Hogwarts, Nico sadly returns to camp half-blood. Although he misses the school of witchcraft and wizardry dearly, he is happy to see his friends again... especially a certain son of Apollo. But when the time comes for Nico, Will, Viktor and Fleur to meet up for their cruise, the two wizards insist that they pick Nico up at camp. There's only one problem with that plan... Viktor and Fleur still have no idea that Nico isn't really a wizard. Naturally, Nico and his friends at Hogwarts are destined to meet again. But with a war brewing in the wizarding world, and an old enemy of Nico's returning to take revenge, how can our hero possibly remain undercover. And how will he be able to protect Harry, destroy horcruxes and defeat his old enemy without failing? One thing is for certain, this just may be Nico's biggest and most dangerous adventure so far.
