As the Doctor, Liv and Helen explore the universe, they come across lost souls, troubled minds and long-kept secrets. From a lonely world with birdsong but no birds, to an English university whose undergraduates tell ghostly tales, and a distant galaxy where a utopian society lives in the shadow of enormous creatures, the TARDIS crew are haunted by echoes of past, present and future... Birdsong by Tim Foley - The TARDIS arrives on an empty world where two scouts await the rest of their colony. Except this world may not be as empty as everybody thinks. There’s a figure in the woods – and a strangely familiar sound. As the Doctor and his friends learn more about the planet’s inhabitants, the birdsong they hear becomes a deadly chorus. Lost Hearts by Lauren Mooney & Stewart Pringle - Michaelmas term, 1903. In one of England’s ancient universities, strange apparitions float between quads and cloisters. While Liv and Helen protect a naïve undergraduate from a sinister society, the Doctor finds a ghost-hunting ally. One who happens to be the era’s foremost chronicler of things that go bump in the night. Slow Beasts by Dan Rebellato - The Doctor takes Liv and Helen to see one of the Wonders of the Outer Galaxy – to Ran-Zoan, where immense alien figures loom over the plains and settlements of the Renn. But the Slow Beasts hide a secret – a secret that, once unleashed, spells doom for this entire world.
