The Doctor's been everywhere and everywhen in the whole of the universe and seems to know all the answers. But ask him what happened to the Starship Brilliant and he hasn't the first idea.

On a lonely stretch of Welsh coastline, a fisherman is killed by a hideous creature from beneath the waves. When the Doctor and Rose arrive, they discover a village where the children are plagued by nightmares, and the nights are ruled by monsters. The villagers suspect that ancient industrialist Nathanial Morton is to blame, but the Doctor has suspicions of his own. Who are the ancient figures that sleep in the old priory? What are the monsters that prowl the woods after sunset?

When the TARDIS is invaded by a holographic marketing scam, the Doctor and Donna find themselves trapped on the Edifice, a purpose-built complex of luxury apartments in space. Their new environs leave much to be desired: millions of beings from across the Universe have been gathered to live side by side in similar apartments. Instead of creating neighbourly affection, it's led to terrible battles being waged in the corridors and on the stairwells.

For Donna Noble, the Andromeda galaxy is a long, long way from home. But even two-and-a-half-million light years from Earth, danger lurks around every corner...

From the desert world of Karris to the interplanetary scrap yard of Junk, the Doctor and Donna discover that appearances can be deceptive, that enemies are lurking around every corner.

Sebastiene was human... once. He might look like a nineteenth-century nobleman, but in truth he is a ruthless hunter. He likes nothing more than luring difficult opposition to a planet, then hunting them down for sport. And now he's caught them all - from Zargregs to Moogs, and even the odd Eternal. In fact, Sebastiene is after only one more prize. For this trophy, he knows he is going to need help.

It is almost Halloween in the sleepy New England town of Blackwood Falls. Paper skeletons hang in windows and carved pumpkins leer from porches. The Doctor and Martha soon discover that this will be no ordinary Halloween.

"The Sunlight Worlds Offer You A Life of Comfort and Plenty. Apply now at the Dalek Foundation." Sunlight 349 is one of countless Dalek Foundation worlds, planets created to house billions suffering from economic hardship. The Doctor arrives at Sunlight 349, suspicious of any world where the Daleks are apparently a force for good - and determined to find out the truth. The Doctor knows they have a far more sinister plan - but how can he convince those who have lived under the benevolence of the Daleks for a generation? But convince them he must, and soon.

The TARDIS is lost in battle on a distant planet. When the doctor sets off in pursuit, Donna is left behind, and finds herself accepting a commission in the Pioneer Corps. Something is transforming soldiers into monstrous beetles, and she could be the next victim.

Donna Noble has never been lucky in love. So when - one day - her Prince does come, she is thrilled to have the wedding of all weddings to look forward to.

But on the big day itself, Donna finds her castle under siege from the darkest of forces, marching at the head of a skeleton army. When it looks like even the Doctor can't save the day, what will Queen Donna do to save her people from Death itself?

Calibris. The spaceport planet where anything goes. Where anyone who doesn't want to be found can be lost, and where everything has its price. Where betentacled gangster Gully holds sway at the smugglers' tavern, Vagabond's Reach. The alien Vacintians are trying to impose some order on the chaos. Soon the Doctor and Donna discover why. An illegal weapon is loose on the streets. A weapon that destroys lives...slowly and agonisingly. The Time Reaver.
