When the TARDIS is buffeted by "time slippage", the Doctor experiences a terrible vision of the end of everything. Tracking the source of the disruption, he takes Rory and Amy to what appears to be an English public school in the 1950s. But the friends discover that there are some very unusual things about Darkstar Academy.

For a start the prefects carry guns, and then there is the strange force field that surrounds the perimeter. Not to mention the foot-long, crab-like creatures with spiny, armored bodies.... The Doctor discovers that the whole place is in terrible danger, but with a swarm of carnivorous creatures on the loose, what can he, Amy, and Rory do to help prevent a terrible disaster?

Britain. The height of the Roman occupation. The Doctor has brought Leela to ancient Norfolk to learn about her ancestors? but has no idea how much of an education she is going to get.

Because this is the time of Boudica?s rebellion. When the tribe of the Iceni rises up and attempts to overthrow the Roman masters.

The year is 16127. Four decades have passed since the colonists of Nerva Beacon returned to repopulate the once-devastated planet Earth ? and the chosen few are finding the business of survival tough.

Far beyond the sterile safety of sanitised Nerva City, transmat scientist Roger Buchman has brought his family to an island surrounded by what they once called Loch Lomond, hoping to re-establish the colony he was forced to abandon many years before.

Aulus is dead. Hailed as a hero of the republic, his sons, Quintus and Titus, have new and heavy responsibilities placed upon them. Lucius, now the most powerful - and sinister - senator in Rome, is keen to manipulate the Cornelii family to achieve his own goals.

Meanwhile, the young Aquila lives in Spain with dreams of becoming a powerful solider to fight for Rome, and discover his destiny, hidden within his Eagled amulet.

In the future as Bova here imagines it, Earth is an ecological nightmare, and humanity may well go the way of the dinosaurs. But overhead orbits salvation. A vast metallic island in space, the Trikon station conducts genetic research too risky to be done on earth - research that could save the planet.

Yet Commander Dan Tighe discovers that the Trikon's major project is espionage. Its international crew is split into warring factions; its scientists - consumed by greed, lust, and drugs - run the lab for their own gain. Murder, intrigue, and romantic jealousy threaten to sabotage the station's crucial work.

Only Commander Tighe can save the Trikon - and only Trikon can save the Earth.

The tendency to synchronize may be the most mysterious and pervasive drive in all of nature. It has intrigued some of the most brilliant minds of the 20th century, including Albert Einstein, Richard Feynman, Norbert Wiener, Brian Josephson, and Arthur Winfree.

At once elegant and riveting, Sync tells the story of the dawn of a new science. Steven Strogatz, a leading mathematician in the fields of chaos and complexity theory, explains how enormous systems can synchronize themselves, from the electrons in a superconductor to the pacemaker cells in our hearts. He shows that although these phenomena might seem unrelated on the surface, at a deeper level there is a connection, forged by the unifying power of mathematics.

It is 1141. In Shrewsbury, civil war is tearing the country apart as the bitter feud between King Stephen and Maud shows no sign of abating.

The young soldier is the foster son of the Prince of North Wales, and a prized possession. In fact, he is so valuable that he can be offered in exchange for Gilbert Prescott, the Sheriff of Shrewsbury, who has been captured by the Welsh.

A swap is duly arranged, but when one of the prisoners is found dead before the transaction takes place, the community learns the horrifying truth: there is a murderer in the monastery. Can Cadfael find out who it is?
