Isabel Eriksson (pseud) (Lind & Co., January 2017), has written a unique and harrowing account of being held captive. The case was reported all over the world and her kidnapper has been compared to both Josef Fritzl and the Cleveland-abductor Ariel Castro, as well as the chilling events in Emma Donoghue’s novel Room. Martin Trenneborg also know as “The Bunker Doctor” is now serving his sentence in prison, while his victim is forced to live under protected identity.
