In the third book of Nicholas Edwards's the Dog Whisperer series, Emily and her dog, Zack learn they can do more than read each other's mind- they can see ghosts!

From the day Emily rescued her dog Zack, they have always shared a special connection. But it's more than special—they can read each other's minds. And since Zack can sense when someone is in danger, they've been using their special power to help save people. But now Emily and Zack have discovered something new. They can see ghosts! And one ghost in particular needs their help. Shocked by her new discovery Emily is determined to find out who this ghost is and why he is haunting her town.
Helping the ghost will help save someone else. But if Emily and Zack are the only ones who can see the ghost, how can they get anyone to believe them? Will they be able to help in time or will the ghost be doomed to haunt the earth forever? Find out in Dog Whisperer: The Ghost.
