Synopsis:
Two years ago, the aliens made contact. Now Cara Sweeney is going to be sharing a bathroom with one of them.

Handpicked to host the first-ever L’eihr exchange student, Cara thinks her future is set. Not only does she get a free ride to her dream college, she’ll have inside information about the mysterious L’eihrs that every journalist would kill for. Cara’s blog following is about to skyrocket.

Still, Cara isn’t sure what to think when she meets Aelyx. Humans and L’eihrs have nearly identical DNA, but cold, infuriatingly brilliant Aelyx couldn’t seem more alien. She’s certain about one thing, though: no human boy is this good-looking.

But when Cara's classmates get swept up by anti-L'eihr paranoia, Midtown High School suddenly isn't safe anymore. Threatening notes appear in Cara's locker, and a police officer has to escort her and Aelyx to class.

Cara finds support in the last person she expected. She realizes that Aelyx isn’t just her only friend; she's fallen hard for him. But Aelyx has been hiding the truth about the purpose of his exchange, and its potentially deadly consequences. Soon Cara will be in for the fight of her life—not just for herself and the boy she loves, but for the future of her planet

Synopsis:
Though the Greek and Roman crewmembers of the "Argo II" have made progress in their many quests, they still seem no closer to defeating the earth mother, Gaea. Her giants have risen-all of them, and they're stronger than ever. They must be stopped before the Feast of Spes, when Gaea plans to have two demigods sacrificed in Athens. She needs their blood-the blood of Olympus-in order to wake. The demigods are having more frequent visions of a terrible battle at Camp Half-Blood. The Roman legion from Camp Jupiter, led by Octavian, is almost within striking distance. Though it is tempting to take the Athena Parthenos to Athens to use as a secret weapon, the friends know that the huge statue belongs back on Long Island, where it "might" be able to stop a war between the two camps. The Athena Parthenos will go west; the "Argo II" will go east. The gods, still suffering from multiple personality disorder, are useless. How can a handful of young demigods hope to persevere against Gaea's army of powerful giants? As dangerous as it is to head to Athens, they have no other option. They have sacrificed too much already. And if Gaea wakes, it is game over.
