Jack's Secret Summer Collection 2 Books set by Jack Ryder

Jack has been dreading the summer holidays - his dad works long hours, and so all he has to look forward to is an empty house. But when his boisterous neighbours, Bruno and Rocco, make it their mission to pull him into an adventure, his life will never be the same again. 

Jack's Secret World: 
Everything changed the day Jack and his neighbours Bruno and Rocco went to explore the old empty house. 
There they discovered a strange girl called Blossom, who introduced them to a world of magic - talking to animals, flying like birds, and even... a doorway to another world, hidden within the ivy-covered walls of the old house.
