Red Shift

In the fifth installment of the "Syzygy" hexalogy, the long-divided clans of lunar survivors reconnect at last, but a century of distrust isn't easily overcome. Determined to forge an alliance between their fractious communities, Ash and Skye undertake a second Earth mission. Old enemies and new revelations await them. As dark truths about the past threaten humanity's fragile chances for the future, only Ash and Skye's evolving partnership can unite the survivors...if it can withstand their own shattered hopes and unthinkable loss.
