Here's what you need to know:
* The Pendragon series is a fantasy adventure series for young adults, following the story of Bobby Pendragon, a teenager who is destined to save the world from the evil Saint Dane.
* The Travellers is not the title of the first two books. The first two books in the series are:
* Book 1: The Merchant of Death
* Book 2: The Lost City of the Sun
* The Travellers is actually the name of a recurring element in the Pendragon series. It refers to the group of people, including Bobby, who travel between different "realms" to fight Saint Dane.
If you are looking for information about the first two books, then you should be looking for "The Merchant of Death" and "The Lost City of the Sun."
