The best part of this book are the two lists of Chivalrous and Romantic duties, taken from real medival litterature.
There are some nice adventures, too - the monster in one of them will be amusing for those who have played a certain horror game, and the murder mystery is a nice change of pace (though the main villain would not use those kind of methods, i think). The marrige adventure seed looks like its worth developing, too.
Still and all, this is just not a classic. It lacks the finishing touches and, worse, feeling of being part of a greater secret whole that makes a proper Pendragon game.
It is NOT the first book you should buy after the rulebook. However, if your Pendragon libary is otherwise complete, its worth a look.
