No one is safe when even the past can't be trusted.

Elcho Falling is under siege from the force of Infinity. Axis must deal with treachery while Maximilian confront the One in the depths of the citadel. Maximilian seems to have the upper hand, but finds his oldest ally's advice disguises a viscious motive.

Meanwhile, everyone has forgotten the Skraelings, who conceal a strange, ancient secret. Now these wraiths face a choice that appears to be no choice at all: the way of Infinity, or allying themselves with the StarMan, whom they have loathed for generations.

In heart-stopping conclusion to this superb trilogy, Maximilian and his friends battle for survival from the malevolent depths of DarkGlass Mountain to the pinnacle of a crumbling Elcho Falling and beyond ... as the past reaches out to seize Axis and drag him into yet another confrontation with his hated brother, Borneheld.
