A piercing scream stopped him in his tracks. By instinct he dropped to a squat. He caught his breath as he had ignored the flooding room and now felt the icy water press against his chest. The noise grew louder as it moved closer to where Theo squatted neck-deep in the frigid water. “Murphy!” Shards of the tile wall behind him flew in every direction as the bullet slammed into it, well above where Theo’s head had previously been.
Seventeen-year-old Theo is caught up in a teenage world of driftboarding and HoloGames until his father’s friend and fellow scientist, Viktor Brack, destroys the laboratory, vowing to use a time machine to rewrite history. Trapped behind sealed doors, Theo promises himself to retrieve a book of secrets and prevent Brack’s evil plot. Theo and his robotic dog, Murphy, follow Brack over 100 years earlier to Nazi Germany. After his own escape from a pit of death, Theo is rescued until forces of evil and Hitler’s Youth attempt to kill him. He is found by sixteen-year-old Gracie, who understands the dangers of the streets. For both teens, the need to survive becomes a reality never touched by Theo’s false world of the HoloGame. Together, the teens take Murphy as they join an underground society, and begin a trek against the evil of Hitler’s regime. Dark alleys, tunnels, and creatures of repulsion force Theo and Gracie into a life-or-death fight to save both past and future.
This book is really good, my teacher is Jimmy Adams (One of the authors of the book) and he said "It'll put you to sleep" but it doesn't it's slow moving at the start but it picks up fast. It is intense in some parts and just when you think everything is going to be fine, then poof something happens. I totally recommend this book if you like historical fiction.
