Marketed as the biggest audio crossover event ever, it featured nine incarnations of the Doctor, as well as Bernice Summerfield, River Song, Romana II and Leela, both the 1970s and 2010s UNIT teams, and Counter-Measures.
On 22 August 2019, the limited edition of the anthology became out-of-print, but the digital version of the limited edition remained available for purchase. On 4 September 2019, a standard edition was made available for purchase on CD that was without the two hours of behind-the-scenes content.
Publisher's summary Edit
Time is collapsing. Incidents of chaos and devastation are appearing throughout the lives of one Time Lord and his many friends – all fallout from one terrible disaster. From Earth's past and present to timeless alien worlds, from the cloisters of Gallifrey into the Vortex itself... The Doctor must save universal history – and he needs all the help he can get.
On a strange ruined world, a renowned archaeologist opens an ancient tomb. Only to find another archaeologist got there first. Professors Summerfield and Song unite to solve a mystery. Then the Eighth Doctor arrives, and things really become dangerous. Because their best friend isn’t quite the man River and Benny remember...
A criminal gang appears to have recruited a member with time-bending powers. It’s a case for the Counter-Measures team – in the 1960s and the 1970s! The Seventh Doctor and Ace have their work cut out to save the day twice over, and make sure Gilmore, Rachel and Allison don’t collide with their past, or their future.
When pockets of temporal instability appear in a Dorset village, UNIT are called in. Soon, Kate Stewart and Jo Jones find themselves working alongside the Third Doctor, while Osgood battles to get them home. But this isn’t the first time UNIT has faced this threat. Only before, it seems that Jo Grant didn’t survive...
Disaster strikes inside the Time Vortex, and the Fifth Doctor is thrown together with someone from his future... someone claiming to be his daughter! Kleptomaniac Time Lord, the Nine, believes it’s his chance to steal something huge. But Jenny just wants her dad to believe in her.
DI Patricia Menzies is used to the strange, but even she is surprised when the eighteenth century itself falls onto her patch. Fortunately, she has the founders of modern policing to help with her enquiries. And when the Sixth Doctor and Charley arrive, they find armed and hostile forces trying to change Earth history forever.

Fallout from the temporal distortions has now reached Gallifrey. To find the cause, Leela and Romana remember travels with the Fourth Doctor to the same world, at different times. The enemy is revealed, and it may take more than one Doctor to prevent the destruction of everything!
