This is five star fan fiction. When one starts to read this book it feels unfair that Lippert "stole" (or maybe better: "used") the world of J.K. Rowling. Gradually, however, this feeling changes to a "but why did Rowling not write about James Potter anyway?". There are enough adventures and themes around James Potter to write about, it appears. With which I want to say that gradually the book grips you (at least if you are a Harry Potter fan) and although you do notice that the style differs from Rowling's style in the Harry Potter books, this only seems natural. After all this book is set 18 years after the last Harry Potter book. And in 18 years , many things change. So far about my feelings while reading this book.The story-lines are very good (no spoilers here). Some are completely revealed in this book, some are just mentioned and will be worked out in later books. The climax of the book is very well written and ends in an unexpected twist. The reader gets a glimpse how this line will be continued in the last chapter.As you may guess I find the book well-written and certainly after you have accepted its right of existence you can hardly put it down. A must-read for Potter fans!
