The novel “The Doors of Eden” by Adrian Tchaikovsky was published for the first time in 2020.

Lee and Mal are very different from each other and yet they become inseparable friends and start investigating together on sightings of creatures that are out of the ordinary. They usually have to put a lot of imagination into writing comments that support the alleged sightings but one day an investigation leads to something all too real and Mal vanishes. Four years later, Lee thinks she lost her when Mal calls her to arrange a meeting.

Dr. Kay Amal Khan is working on some research in physics that is supposed to be very theoretical but someone seems interested in it the wrong way. The woman works for the government and the issue involves national security, so Julian Sabreur of MI5 has to protect her. His investigation quickly becomes complicated because among his suspects is one person who doesn’t look entirely human and another who is believed to be dead. Soon, the developments indicate that there are parallel Earths and there are various forces at work with unknown agendas.
