Some excellent parallel universe fictions include 'The Man in the High Castle' by Philip K. Dick. It presents an alternate history which is like a parallel universe where the Axis powers won World War II. 'Doctor Strange' in the Marvel Comics also deals with parallel dimensions and universes quite a bit. In addition, 'Cloud Atlas' by David Mitchell has elements that can be related to parallel universes as it jumps between different times and places that seem to exist in different realities.
One of the great ones is 'The Dark Tower' series by Stephen King. It involves different worlds and a complex multiverse. Another is 'Sliders', which is about a group that slides between parallel universes. And 'Fringe' also delves into parallel universe concepts with its own unique take on the idea.
Well, 'His Dark Materials' by Philip Pullman is a wonderful parallel universe fiction. It has multiple worlds with different rules and beings. 'The Chronicles of Narnia' can also be considered in a way, as the different lands in Narnia are like parallel universes compared to our own world. Then there's 'A Wrinkle in Time' which takes the main characters through different dimensions that are sort of like parallel universes.
