Timestorm: Tempest 3

Tempest Agent Jackson Meyer's back. Just ... he barely survived the time jump forward to the year 3200 and another jump will probably kill him.

Imprisoned by Eyewall, an opposition organization determined to shape the future according to their will, regardless of the human cost, Jackson needs to decide once and for all what really matters to him. Trying to save the people he loves - including Holly, one-time love of his life and in this timeline at least an Eyewall recruit - or risking everything to try to prevent this horrific future from ever taking place. But things are not always as they seem. And as the truth unravels, Jackson is forced to realise just how much love costs.
