In desperation, he heads Walker into a squall, hoping it will give them cover---and emerges somewhere else.Familiar landmarks appear, but the water teems with monstrous, vicious fish. And there appear to be dinosaurs grazing on the plains of Bali. Gradually Matt and his crew must accept the fact that they are in an alternate world---and they are not alone. Humans have not evolved, but two other species have. And they are at war.With its steam power and weaponry, the Walker's very existence could alter the balance of power. And for Matt and his crew, who have the means to turn a primitive war into a genocidal Armageddon, one thing becomes clear: They must decide whose side they're on.

    But now he needs help from the Doctor, Romana and K-9. When he left Gallifrey he took with him a few little souvenirs—most of them are harmless. But one of them is extremely dangerous.The Worshipful and Ancient Law of Gallifrey isn’t a book for Time Tots. It is one of the Artifacts, dating from the dark days of Rassilon. It must not be allowed to fall into the wrong hands. The sinister Skagra most definitely has the wrong hands. He wants the book. He wants to discover the truth behind Shada. And he wants the Doctor’s mind...Based on the scripts for the original television series by the legendary Douglas Adams, Shada retells an adventure that never made it to the screen.

    It’s even harder for a robot named Mack Megaton, a hulking machine designed to bring mankind to its knees. But Mack’s not interested in world domination. He’s just a bot trying to get by, trying to demonstrate that he isn’t just an automated smashing machine, and to earn his citizenship in the process. It should be as easy as crushing a tank for Mack, but some bots just can’t catch a break.When Mack’s neighbors are kidnapped, Mack sets off on a journey through the dark alleys and gleaming skyscrapers of Empire City. Along the way, he runs afoul of a talking gorilla, a brainy dame, a mutant lowlife, a little green mob boss, and the secret conspiracy at the heart of Empire’s founders---not to mention more trouble than he bargained for. What started out as one missing family becomes a battle for the future of Empire and every citizen that calls her home.

    Years before they enter orbit, their approach will be announced by the flare of a thousand flames in the sky, their ships’ huge engines burning hard to slow them from the vast speeds needed to cross interstellar space. These foreboding lights will shine in our night sky like new stars, getting ever brighter until they outshine even the sun, casting ominous shadows and banishing the night until they suddenly blink out. Their technology is vastly superior to ours, and they know they cannot possibly lose the coming conflict. But they, like us, have found no answer to the destructive force of the atom, and they have no intention of facing the onslaught of our primitive nuclear arsenal, or the devastation it would wreak on the planet they crave. So they have flung out an advanced party in front of them, hidden within one of the countless asteroids randomly roaming the void. They do not want us, they want our planet. Their Agents are arriving.
