The Lost Hero

Recently, I have read, and finished a book called The Lost Hero, by Rick Riordan, also the author of the Percy Jackson books. The Lost Hero is the first book of a new series, which takes place after the final book in the Percy Jackson Series. There are three main characters, Jason, Piper, and Leo. Each is experiencing something very strange. Jason has lost his memory, so he can't remember anything. Not even his own friends. So after a freak storm hits the wilderness school they were going to, things start to get even weirder. Apparently, their teacher, coach Hedge was actually a saytr half goat, half human, and was protecting them. Saytrs are from Greek mythology, and now Jason is seeing one face to face! Jason also has a sister, but he doesn't remember her either. Now, Piper has a famous actor for a father, however he has been missing for three days. She doesn't understand why her boyfriend (Jason) has suddenly forgot who she is. After the freak storm takes their "protector" (coach Hedge) they are whisked away to a place known as Camp Half-Blood, they are supposedly safe. From what? Now, for the last character, Leo, he is really good with tools, so after meeting a bunch of kids who have the same interests, he feels like he's in heaven. But eventually, something weird happens; he is immune to fire! And if that wasn't weird enough, Leo and his friends are supposed to have gods for parents! What is going on? Where is Percy Jackson (who wasn't present at all in the whole book), and who are their parents? Read the book yourself to find out.
