Jake the Time Jumper: The Portal Walker, Book 1: The Portal Walker, Book 1

A glitch in time. A lost artifact. And a sister who may have already changed history.

When teen coder Jake Parker is ripped from his world by a mysterious time rift, he crash-lands in a brutal prehistoric era-separated from his sister, stripped of technology, and hunted by nature itself.

Facing lethal predators and a tribe of ancient humans who see him as either threat or omen, Jake must adapt fast. His only hope for survival lies with Amna, the fierce young leader of the tribe who saves his life but questions his purpose. As Jake struggles to earn their trust, he uncovers echoes of a deeper mystery-one linked to a powerful artifact and a time anomaly that may not be random.

Could Emma have traveled through time too? And if so... what has she changed?

As survival transforms into something far more dangerous, Jake must confront a world without logic, code, or control-and decide who he is when the future depends on the past.

Sometimes the key to the future... is buried in our origins
