The House Guest by Eleanor Nilsson

This book has been rated as a top read for boys and girls would love it too. It's another Australian gem I couldn't put down. Gunno and his gang regularly skip school and raid houses for fun, stealing cash only. When Gunno and the gang break into The Big House, he finds that his life changes as this house in the valley is different and it holds some fascination for him. He is continually drawn back to it. and starts visiting regularly thinking of it as his house; he loves the little dog there and day by day is learning about the lives of the owners. And there's also Hugh's room, but where is Hugh?His bedroom is musty and his books and belongings are all covered in dust. Eleanor Nilsson first thought of the story of Gunno and Hugh after she saw an old rambling house near Adelaide. The house seemed welcoming yet elusive and mysterious. This is the house in The House Guest. The dog in the story was inspired by Lochie, Eleanor's own Shetland Sheepdog.
