Abductors

From a distant future, a transdimensional raider has invaded the here and now. In his brutal world, knowledge and technology have been lost. He plans to change this by capturing and abducting knowledgeable people from our present, something he already tried once back in 1952 when Anne’s grandmother was young. She kept quiet about this and so her granddaughters confront danger unwarned.
Anne’s hyper-intelligent little sister vanishes. To seek her Anne must cross space and time and follow her into a gruesome dark world. A sword wielding enforcer whose task it is to kill all those who break the barriers between the dimensions is already on his way.
