Brenda Heller & Jimmy Adams 10605 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. Jimmy Adams and Brenda Heller are teachers who met at the high school in Derby, Kansas. Jimmy lives in the city and was born in Pennsylvania. Brenda lives in the country and was born in Kansas. However, both enjoy running, the outdoors, and teaching teens. Each holds a degree in history, so when Jimmy had an idea to blend the truth of history with a flair of imagination, the series began. TimeWorm and the books to follow bring the events of yesterday as alive and daring as the moments in which they first occurred.
