'Reminiscent of The Martian and World War Z' PIERCE BROWNA twenty-story-tall metallic figure appears in the middle of Regent's Park.
The caretakers at London Zoo notice it first at around 4am.
The figure, or robot, bears a great resemblance to the UN robot known as Themis . . . Who made Themis? It's been ten years since Themis - a giant alien metal robot - was revealed to the world by Dr Rose Franklin.
It now stands at the heart of the Earth Defense Corps - in case the makers of Themis return to claim it. Why did they leave it here? Rose and her team are still seeking answers to Themis's origins when a second and even bigger robot appears in London's Regent's Park.
A military response backfires, reducing half the city to bare earth. And what if they come back? As more robots appear across the world, Rose knows it's a race against time to discover where they've come from, what they want and - most importantly - how to stop them . . . 'Captivating' BUZZFEED'A sheer blast from start to finish.
