Mystery at Deep Ravine

One of Jake's classmates, Byron Markham, hates Indians. His great-great-grandfather, a soldier with Colonel George Armstrong Custer's Seventh Cavalry, died at the hands of the Sioux Indians in the Battle of The Little Bighorn. Byron's secret trouble is that his great-great grandfather's body--along with 27 others--was never found to prove that he was not a deserter. While continuing mind-expansion experiments with Dr. Carolyn Kramer and her daughter Pamela, Jake is transported back to Custer's famous battle. He discovers a clue that might answer the riddle of the missing 28. Jake doesn't know that computer-whiz Byron is plotting to use Jake's power to answer the Markham family's puzzle and that he is willing to risk Jake's life to do it. Byron convinces Jake to use his power, then, following his computer-captured clues, Jake, Byron and Pamela sneak off to find an abandoned mine. While digging, they cause a cave-in. Pamela is thrown clear but is disoriented. Jake and Byron are trapped and Byron isseriously hurt, with only Jake to rely on to keep them both alive until help arrives...Pirone, James is the author of 'Mystery at Deep Ravine' with ISBN 9780880922951 and ISBN 0880922958.
