'John Chisholm and his two schoolboy sons, Peter and Kane, set out in Queensland to find Paradise Valley which had been visited by John Chisholm's father in the early days. They discover it, and in so doing meet a mysterious tribe of aborigines, and fall into a series of most hazardous adventures.
'This is the dramatic portion of the story, but under it, and giving additional interest to the book, is much natural lore and information, and good descriptive matter that contains much useful information about northern Australia.'
