The novel “In The Blood” by Jenny T. Colgan was published for the first time in 2016.
The Tenth Doctor brings Donna Noble back to her time but things quickly start to go wrong. Donna wants to spend some time with her old friend Hettie but finds her grumpy even though her life is supposed to be perfect. She’s not the only person to engage in that type of behavior, and internet trolls increased significantly. However, trolls also began to die.
The Doctor thinks something abnormal is happening to people, stimulating their negative instincts. Unfortunately, someone opened a bar in front of the Tardis and is ready to use violence to prevent him from entering it. The Doctor and Donna must use conventional means to travel around the world in search of the cause of what is happening.
