The cover was made by Tinypancakes on tumblr, not me! I was searching for a cover for a week and I fell in love with this one.
Jack is a simple Youtuber in Ireland that has recently been dumped by his girlfriend. He feels alone and is not having as much fun with his job of playing video games as he used to be. Things get worse when he notices that some things are going missing. Nothing important has left his possession, but it seems that small bits of food, soap, and medicine are the main targets. Jack thinks that there is something else living in his house with him, something smart and cunning. He wants to find it and meet it face to face.
Mark is a borrower that has moved into Jack's home. Mark sees that Jack is gloomy all the time and doesn't know why. He wants to comfort the human, but there are rules in place that prevent him. His punishment for breaking these rules: he has to leave Jack's home and can't ever see him again. But Mark doesn't want to leave, he wants to watch Jack be happy and enjoy his life. Jack may be loud, but he's funny and is such a kind and loving person. If Mark could show himself to Jack and meet him formally, Mark would be one of the happiest people in the world.
