It's always been just Ryder and his mom. But on the way home from Ryder's baseball practice, everything comes to a halt. An accident sends his mom to the hospital, and now she is fighting for her life. So Ryder goes on a search to find his father, determined to help pay for the expensive operation to save his mother's life. But with only a signed baseball and a letter as his clues, and the help of his next-door neighbor and a New York City firefighter, will everything fall into place in time, or will Ryder become a lost boy forever? New York Times bestselling author Tim Green knocks this one out of the park, combining heart and baseball to create a story that readers will never forget.
