Heroes of Olympus. Book 1. The missing hero. Riordan R.

Jason woke up on a school bus, holding a very beautiful girl by the hand. The guy from the front seat called himself his best friend... But Jason has a problem: he does not remember any friends or himself, as if someone erased his memories with an eraser. After a couple of hours, it turns out that in his pocket Jason wears a magic coin that turns into a sword, that he knows how to fly... and that some incredible creatures, the spirits of the storm, firmly intend to kill him.

Fortunately, a rescue team from the half -blood camp has already flown up for Jason and his friends. Places specially created for the protection and training of people such as they are demigods, mortal children and Olympians. Annabeth Chase, the daughter of Athena, will have to find out how the appearance of new demigods and the mysterious disappearance of her friend Persia Jackson is connected...
