Book I of The Inconstant Moon trilogy. Erik Morrison doesn't want to be on the Moon. From the time he sets foot in Villanueva Base - the multilevel, underground city beneath the lunar surface - he feels out of place and out of touch. He just wants to do a good job as the Entek Coporation's new Site Co-ordinator and get back to terra firma as soon as possible. But there's more than business as usual going on here. There's a dangerous game of greed and power in which Morrison is just a pawn. But he's about to uncover a shocking revelation that some want exposed and that some will do anything to keep hidden.
