Master! Planet Doom

The Master and Vienna Salvatori form an unlikely alliance when they’re forced into joining an expedition to a forbidden planet. Accompanied by elite marines, government scientists and a corporate mercenary with access to some very old UNIT files, they go in search of an ancient, subterranean labyrinth infested by an alien lifeform the Master knows all too well.

3.1 Basilisk by Robert Whitelock - Vienna finds herself prisoner on a warship. Private contractors working with the military's scientific division want her to help them resurrect the Master. Why? Because they need a guide into the bowels of a nameless planet... and the Master is their man.

3.2 Axos Rising by Barnaby Kay - The Master and Vienna are joined at the hip as they head into the alien labyrinth. But deadlier things than ancient booby-traps await them. Deep in the subterranean darkness, they discover the terrifying entity that has been waiting for millennia to be set free. Vienna is horrified... but the Master knows an opportunity when he sees one.

3.3 Hellbound by Robert Valentine - With the countdown ticking, the Master and Vienna are desperate to escape, but if Axos gets loose, the entire galaxy is doomed. Vienna needs a miracle, and perhaps she's found one. But probably not the miracle she was expecting.
