Fright Train (A Weirdville Book). Weirdville, #3

Charlie's parents drop him off at the train station so he can visit his grandma in Weirdville. It's a cold winter evening, so when his usual train is cancelled at the last second, Charlie wishes he'd stayed home. An hour later, shivering from the cold, he climbs onboard the next train to Weirdville, even though he'd rather not. It looks like something straight out of the nineteenth century, as if it used a time machine to arrive at the station. His shivering doesn't stop, for soon after Charlie boards, he realizes just how right he was to be wary of this strange train.
Something is seriously wrong with all the people onboard. If only he could figure out what was going on. If only he could get off the train.
