A Tale of Five Earths — Stephen Gray

Rowan's sudden gift of teleportation is only the beginning as he embarks on a quest to recover the component parts of the dreadful device, capable of ending reality as we know it. Along the way he recruits the help of his own inter-dimensional counterparts. Can Rowan reassemble the device and deliver it to the only place in the multiverse beyond the reach of his enemies? Robots, sentient dinosaurs and a post-apocalyptic turf-war, A Tale of Five Earths is a science-fiction roller coaster ride across parallel worlds.
