Playground of Time - Carl Jones - Bog

Four strangers, Itzli, Zarah, Jack, and Kolton from across time and space make an unlikely team when thrown together onto the planet Null. Each of them separated from their reality through what is vaguely known as The Leap, a galaxy-wide anomaly that tears apart the fabric of space. Marooned on an uncharted planet, the four must figure out how to cooperate, fight off native wildlife, and avoid encounters with a malicious group known as The Forgotten. Unsure if they will find a way back home, alliances are found in unlikely places and secrets force decisions not easily made. Mysteries deep within The Forgotten's base reveal they are up to something sinister that may threaten not only the fate of the planet, but the universe itself.
Meanwhile, Dragg, the leader of The Forgotten, has created a time machine from the husk of a derelict starship which he believes will bring him back to his family he lost when he was taken to Null. That was forty years ago, however, and Null has not been kind to him and his crew. He'll stop at nothing to get his family back, but playing with time has unforeseen consequences and it's up to the four friends to stop Dragg's annihilation of the planet through battle and a little help from the inside.
