Five stars and yes ...

although I readily admit that this is probably the fan who talks rather than informed reader!
I had found the tome 5 rather talkative and fairly flat, The Half-bloof Prince revives for me with the quality offered by the Goblet of Fire, Volume my favorite to date.
It is clear, it is far from spectacular annual and confrontations offered by the first installment ... For me it is rather logical, Harry grew up, their concerns, their actions and choices are now more mature.
This volume is, in reality, a showcase for the unveiling of the causes of the story: Why Harry, why a talented but tortured sorcerer became Lord Voldemort (you learn a lot about his past), and even the character of Snape (Snape English) begins to show its true face.
I read the book a few hours and the plot remains for me very well "tied".
