June was a trying month for Lukas-a month of endless waiting. Once school was done for the year, Lukas would join his cousin KC on "The Farm" where his father and his Uncle Ben had grown up. Uncle Ben had just bought a new horse named Nugget. Now both KC and Lukas had a horse to ride, and a summer full of adventure beckoned. But then KC told Lukas about something new. A "ghost train" had been sighted, running on the branch line not far from The Farm. And not just any ghost train. This was the Ghost Train, a train with ties to Lukas' very own family, a train long absent but now mysteriously reappearing when the moon was full. ... Before long, Lukas and KC decide to embark on a quest for the mysterious spectral locomotive-a quest that proves all too successful when the cousins find themselves right in the path of the onrushing Ghost Train, with their lives hanging in the balance!
