Wetworld by Mark Michalowski
When the TARDIS makes a disastrous landing in the swamps of the planet Sunday, the Doctor has no choice but to abandon Martha and try to find help. But the tranquillity of Sunday's swamps is deceptive, and even the TARDIS can't protect Martha forever. The human pioneers of Sunday have their own dangers to face: homeless and alone, they're only just starting to realise that Sunday's wildlife isn't as harmless as it first seems. Why are the native otters behaving so strangely, and what is the creature in the swamps that is so interested in the humans, and the new arrivals? The Doctor and Martha must fight to ensure that human intelligence doesn't become the greatest danger of all.
Sick Building by Paul Magrs
Tiermann's World: a planet covered in wintry woods and roamed by sabre-toothed tigers and other savage beasts. The Doctor is here to warn Professor Tiermann, his wife and their son that a terrible danger is on its way. The Tiermann's live in luxury, in a fantastic, futuristic, fully-automated Dreamhome, under an impenetrable force shield. But that won't protect them from the Voracious Craw. A gigantic and extremely hungry alien creature is heading remorselessly toward their home. When it gets there everything will be devoured. Can they get away in time? With the force shield cracking up, and the Dreamhome itself deciding who should or should not leave, things are looking desperate...
Forever Autumn by Mark Morris
It is almost Halloween in the sleepy New England town of Blackwood Falls. Autumn leaves litter lawns and sidewalks, paper skeletons hang in windows, and carved pumpkins leer from stoops and front porches. The Doctor and Martha soon discover that something long-dormant has awoken in the town, and this will be no ordinary Halloween. What is the secret of the ancient chestnut tree and the mysterious book discovered tangled in its roots? What rises from the local churchyard in the dead of night, sealing up the lips of the only witness? And why are the harmless trappings of Halloween suddenly taking on a creepy new life of their own? As nightmarish creatures prowl the streets, the Doctor and Martha must battle to prevent both the townspeople and themselves from a grisly fate...
