Superior Beings

Peri hasn't been time-travelling for long and is just getting used to the Doctor and the TARDIS. The Doctor's such a sweet, friendly guy and the TARDIS keeps leaving her little presents, which is neat. When the TARDIS takes them to a party of super-advanced humans on a pleasure-planetoid in the far future (even neater!), Peri falls for the charms of the local hunk and finds herself flying headlong into a quite different form of time-travel...

The Valethske are hunters. They prefer human flesh to any other. They've been sleeping for centuries and now they're hungry. The Doctor, teaming up with shamed xenologist Aline Vehlmann, finds himself caught up in the machinations of the vulpine hunters, and discovers that fresh meat isn't all they're after...

For deep beneath the surface of a strange and beautiful garden-planet, something is waiting. Something that Aline believes is her destiny. Something for which the Valethske have been searching for centuries. And as events escalate into a desperate fight for survival, who will prove themselves the superior beings?
