I listened to it as an audiobook on iTunes sometime between 2011 and 2014.
It was a near-future sci-fi story, in English, with one narrator.
The plot involved an alternative dimension / other world that people could physically travel to. They did not use a spaceship. Instead, they used a man-made, high-tech machine/chamber/room, possibly located underground or inside a research facility. People had to sit down and strap in before travelling.
The main characters were several people, mostly scientists, with some military involvement. Other countries were mentioned, possibly including China.
The other dimension had a name, but I do not remember it. At first it appeared like a paradise, and near the start of the book one scientist was so fascinated by its beauty that she removed her helmet, alarming her colleagues. Travellers had to wear environmental suits / helmets.
Later, the dimension was revealed to be crumbling, decaying, and unsafe. The landscape may have been red or orange, with decaying abandoned buildings.
There were hostile creatures there, described in my memory as dark/black, wraith-like ghosts or spirits.
A fair way into the book, there was a chapter where a team was in a large transporter/vehicle, possibly something like a truck that had been brought into the other dimension, and they were trying to outrun the wraith-like creatures.
