The Puzzling Code

10 to 15 year olds. Adam Martin, a thirteen year old boy on crutches, lived with his grandfather in a rundown part of a city. Even so, he maintained a happy outlook on life. He was smarter than most of us and used his powerful brain to solve mysteries that kept popping up around him. He loved those that had puzzles or secret codes associated with them. In Book One - the Puzzling Code - he and his grandfather take on a team of foreign agents who are trying to keep them from finding a valuable stash of loot hidden one hundred years earlier and only recently made known to them in a secret code discovered in one of his grandfather's old books. Lots of good conversations between Adam and his grandfather in and among action, danger, and adventure.
