John Harding and Doug Lionheart are the last two men alive in the outer planets after a sudden, literal bloodbath. Lionheart decides to look for other survivors and lead a desperate retreat to the only safe place left- Earth.

But Harding has other ideas. Visions haunt Harding's sleep, replaying the death of his closest friend John Leadon at the fangs of invading vampires. It all makes perfect sense, except... Harding never actually saw his friend die.

When the two men suddenly find themselves sharing their ship with a rogue vampire, Harding sees an opportunity to turn back the clock and save Leadon.

But will his trust in the vampire Grymeve Parker save his friend, or doom humanity in all eras to be food for the vampire horde?
