Arthur Templar and the Curse of the Nibiru

Twelve-year-old Arthur Templar knows he is different.
But he does not know he is a Timethreader.

He is not alone, even though he often thinks he is.
Arthur's two best friends also have unique psychic powers.
Erin is a healer with heightened psychic empathy.
Torin can remotely view hidden places from anywhere in the galaxy.
Are their psychic and mind-reading powers enough to stop a dangerous Nibiruan mining operation from destroying Elderberry Valley and the star people living there?
The young detectives are surprised, deceived and misdirected by the devious, cunning Nibiruan criminals.
Can Arthur and his friends devise a plan to defeat the other-world criminals and save their precious valley?

How?
