I have just finished reading Terry Brooks lastest Shannara book: Morgawr. It is a good read, which looses none of the pace or atmosphere of the previous Shannara books, and which beats the 'Antrax' for being a good read.
This books brings the series of books: Flight of the Jerle Shannara to a conclusion, introducing new plot twists, and new (if hinted at charecters) into the narative. He also keeps up the pace until the very end, keeping the reader on edge until the last line of text.
Where the book does fail is with what Terry Pratchett would call 'Navaritium' the stuff of stories, which hold stories together. TB's charecters often find themselves falling for old tricks, and rather obvious plot avenues. This makes the reading a little disapointing at times, especially as it makes you want to shout 'He's behind you'. However these are thankfully few and far between.
The book ends well (if obviously), and is obviously a spring-board for future Shannara books, however I do wonder whether it will be possible to keep the 'fantasy fiction' feel to the stories now that TB has introduced quite advanced technology into the 'Four Lands'.
To really appreciate the book, one would need to read the other Shannara books first, as these provide the background and narrative elements to the story to make it whole. However, I would imagine that only really dedicated TB fans would really want to read this book in Hard Back.
