Ghostly Park [EPUB ebook] 

The Monster Files is back with another exciting case.
Miller is on his way to Summer Camp and he is leaving Smith in charge – or you could say, by herself. On top of that, Smith has done something she swore she would never do: joining the track team.
One night, Smith’s summer takes a turn to the strange side, as she meets a young boy named Charlie. He warns her to stay far away from the park before she ends up like the others. Not one to be easily scared, Smith brushes the encounter off as a prank.
When things keep getting weirder every time Smith goes to the park, she decides to investigate it, and Charlie. But is there some lost secret in the park? Is the place haunted, or is it all just a big prank? Who knows, but Smith intends to find out the truth.
