I am a fan of Gerald Morris' work, and this is a delightful addition to his Squire's Tales Series. The story follows an innocent who goes in search of his father after the death of his mother. Supporting characters include new characters Galahad, Ellyn, Bors and Lionel, and old favorites Gawain and Terrance. There are no fools in this book, a change for the series, and I think it is an improvement. Everyone seems to have a motivation; each of them is trying to do right in his own way (some failing miserably), which is appropriate for the subject matter. Yes, admidst the light banter, there are suprisingly deep themes. Gerald Morris explores the nature of right and wrong and the purpose of existence, and I think he pulls it off nicely. This book can be enjoyed by children for its wit and adventure and by adults for [the same reasons plus] the questions it raises.
This book is a bit different from the rest of the series in it seems to set itself up for a sequal. It is much shorter than previous novels, and I suspect that this book may be half of the original story idea. Lancelot, for instance, is mentioned at the beginning of the book, but he never appears later on, even though the events of the book could be really close to home for him. A new bad guy character is introduced, and some characters are warned about him, but afterwards he disappears from the narrative. You should not take this to mean that the book has plot holes. It is more a sense that future events in the series are being foreshadowed here, and I look forward to reading that book as well.
Now, as a bonus, I will talk about my favorite aspect of the series as a whole--the cover art. This book is as ridiculous as ever (part of the charm), a hodgepodge of victorian clip art with visible scan lines. The artist has depicted a scene found nowhere in the book, complete with at least one unidentifiable character and a mysterious green glow immenating from the door on the right (a grossly misinterpreted "fair unknown" perhaps?) All this is hillarious, of course, but sadly, it does not top the previous book, The Lioness and her Knight, which must be seen to be appreciated.
