This is a very well-written and seamanlike book. The hero is young Harry Collingwood, the same as the pseudonym of the author. His father has not returned from a previous voyage to sea, and is presumed to be lost. There are also some indications that somewhere in the Pacific there is a "Treasure Island" to be found.
A beautiful and very fast cutter is built. This part of the book is where the author excels, as shipyard work is where he works for his day-to-day bread.
They travel to the Pacific, having various adventures on the way, even to the point of acquiring a charming young lady passenger, with whom the hero falls in love.
We will leave you to find out what happened then, but we can be sure you will enjoy the book.
