Doctor Who by Stephen Gallagher

I am Biroc. The shadow of my past... and your future.
Warriors' Gate
In this new-to-print, expanded novelisation of the classic 1981 adventure, the TARDIS is caught in a collapsing void between two different universes - and the 4th Doctor, Romana and Adric must enter into a dangerous alliance with the Tharils - a race of enslaved, time-sensitive aliens. The consequences are explored in two further short stories...
The Kairos Ring
Now allies of the enslaved across all creation, Romana and the Tharil Laszlo ride the time winds in search of the sinister Sluagh - aliens who retool the dead as deadly warriors.
The Little Book of Fate
Searching for the source of a scream across time, the Eighth Doctor investigates a most unusual carnival freak show in the north of England - where a figure from his past awaits him.
Not one story but three, from one of classic Doctor Who's most original voices - Stephen Gallagher, author of the original screenplay for Warriors' Gate.
