The Secret in Vault 13
The Doctor has never faced a challenge quite like this…
In the coldest spot in the universe is the Galactic Seed Vault. For generations it has existed to store and preserve examples of plant seeds from across the galaxy, ensuring that in the event of planetary catastrophe, the seeds will survive.
And at its heart lies a secret. Vault 13.
Unopened for millions of years, no one is sure what it contains. There are rumours of a great treasure, and a terrible weapon.
Now the Doctor and her companions are in a race with an ancient order known as the Gardeners of Tellus to unlock the vault. Whoever gains access first will discover the horrifying secret of the Genesis Seed.
