A new hardback book, The Gold Archive: Invasions of Earth: A Secret History, will be released on October.

Written by Mike Tucker and Steve Cole, the book is billed as “the ultimate guide to every Doctor Who Earth invasion.”For over half a century the world has been kept safe from alien invasion by the tireless work of UNIT – the Unified Intelligence Taskforce. Finally, that story has been uncovered.From the early days working in secret under the command of Brigadier Lethbridge-Stewart to the new, modern UNIT organisation under the leadership of his daughter Kate, this secret history exposes the many threats ranged against our world – and how UNIT has saved humanity time and again.Carefully curated from the top-secret, maximum-security heart of UNIT itself, this never-before-seen account includes declassified case files spanning five decades, technical schematics of recovered alien technology, previously unreleased press reports and testimony from UNIT personnel who witnessed events first hand.

The book also features a good deal of input from the current Fifteenth Doctor.

You can pre-order The Gold Archive: Invasions of Earth: A Secret History ahead of its release in hardback on 31 October 2024.
