Watchers is a new audiobook, written and narrated by Matthew Waterhouse and featuring Nicholas Briggs as the Daleks.
When the TARDIS is trapped in the Vortex, the Doctor and Adric realise that something immensely powerful is draining time itself from the universe. The wrecks of other ships – the products of countless experiments in time – exist in a fused cluster in the Vortex. None of them can escape and many of their crews are dead.
