Alex Faraway And The Battle For Mars - Alex Faraway, #3

In this third book in the 'Alex Faraway' Series, it has been 4 years since Alex Faraway blasted off from Earth to join his once-missing father on Mars. Because of his past heritage with Mars, Alex transformed into an Earthian with all the new abilities his Martian cousins possess. The orphan Martian, Rainah Onyodee, has found a new home with Alex's mom, Elizabeth, and is finishing high school in Delta Town.
Old Elliot, the astronomer, has settled down with Rosie in her café where Elizabeth works and where he keeps a roof-top vigil each night, tracking the approach of Planet X (the Nethlin world) as it nears its 10, 000 years encounter with Mars. But, a new and more sinister entity has joined forces with The Others in order to fulfill their ultimate end-game: The complete destruction of the hibernating Martians, still asleep in their Time Tombs under the sands of Mars, as well as the Mars Biosphere Dome which holds all the surviving plant-life from a time when Mars thrived with life 10, 000 years ago.
And the Earth-sized Nethlin World is all but upon Mars, bringing with it shattering gravity-waves that will not only bring fresh upheaval upon that smaller world but, also, the Great Change in its orbit which will be shifted back to its former, closer distance from the sun. When that happens, the Martians will awaken and new life may have a slim chance once more. But the Dark Man has stolen the all-important Map of the hidden Time Tombs and now The Others are on the hunt for all of them.
Catch up with Alex Faraway as he races to uncover the remaining mysteries of the ancient people of Mars and of his own father's murky passed involvement with all the dark forces converging upon his new Homeworld. The exotic radiation from his symbiotic Martian-made Luss weapon is transforming Alex, as well, and this time, it will change the Earthian boy into something even other than a Martian.
