"We believe that death should always be part of life."

The Doctor's last three visits to the scattered human colonies of the third millennium have not been entirely successful. And now that Ace has rejoined him and Bernice, life on board the TARDISis getting pretty stressful. The Doctor yearns for a simpler time and place: Earth, the tropics, the early twentieth century.

The TARDIS lands in Haiti in the early years of theFirst World War. And the Doctor, Bernice and Ace land in a murderous plot involving vodoun, violent death, zombies and German spies. And perhaps something else -- something far, far worse.

Ace raised her blaster. "You've already killed me once, girl," Kreer said. "Didn't you learn anything from that?"

When Bernice asks to see the dawn of the space age, the Doctor takes the TARDIS to the United States of America in 1957 -- and into the midst of distrust and paranoia. The Cold War is raging, bringing the world to the brink of atomic destruction.

But the threat facing America is far more deadly than Communist Russia. The militaristic Tzun Confederacy have made Earth their next target for conquest -- and the aliens are already among us.

Two nuclear warheads have been stolen; there are traitors to the human species in the highest ranks of the army; and alien infiltrators have assumed human form. Only one person seems to know what's going on: the army's mysterious scientific advisor, the enigmatic Major Kreer.

The Doctor pointed at Bernice. "The wench's mind is addled", he said. "Arrest her before she spreads her ungodly heresy".

The TARDIS is caught in the gravitational field of a dark star. The Doctor and Bernice are forced to evacuate, and find themselves stranded in medievalFrance - a brutal time of crusades and wars of succession.

As the Albigensian crusade draws to its bloody conclusion, men inflict savage brutalities on each other in the name of religion. And the TARDIS crew find their lives intertwined with warring Templars, crusaders and heretics. While the Doctor begins a murder investigation in a besieged fortress, Bernice finds herself drawn to an embittered mercenary who has made the heretics' fight his own. And they both realise that to leave history unchanged they may have to sacrifice far more than their lives.
