Before I forget, I've neglected in my reviews of the first two books to mention the cover art for these editions, which is, to be honest, stunning in all three cases. They're worth buying for that alone, a step in quality above the later reprints. On the other hand, the book is good enough to buy even if it had covers drawn in crayon - assuming you've read the other two. This book is heavily reliant on knowledge of the previous two, and though certain parts of the previous novels are interwoven into dialogue here to provide that knowledge, it is not always entirely effective. That aside, given you've read the first two books, this is a thrilling yarn, living up to the legacy of its predecessors with aplomb.
The book reunites Tas and Caramon,who have managed this time to travel into the future. But in contrast to their more light hearted adventures in Vol I, they tend to act with more of a driven purpose - the halting of Raistlin is now less of an 'adventure' and more an act of desparate need for both of them. The development here of Caramon, whose anger gradually transmogrifies into grief, pity and finally resignation to his brothers self-serving evil, shown throughout, is particularly well done.
In the meantime we are shown Crysania and Raistlin as they proceed into the Abyss, and the tragic near-love between them is finally given the room it needs to become interesting. Crysania continues to struggle to 'redeem' Raistlin even as she loses her own faith, while Raistlin's manipulation of Crysania constantly suffers as he finds himself attracted to her. Alongside this the reader is given a close up on some of Raistlins inner demons, which make for darkly entertaining reading.
Interestingly the book also gives us some time with Lord Soth, Knight of the Black Rose, and Kitiara. While the scenes above can often bestrangely tender, these remain almost chilling, though the dynamic between the two as they plan an attack in the 'present' world is fascinating, especially when balanced aginst Tanis, leading the action-laden defensive to prevent any aid from reaching Raistlin (though who actually wishes to do so is an issue within the text itself).This acts as a nice counterpoint to the more personally introspective threads (though Raistlins journey in the Abyss is not exactly quiet either)
The three threads converge in the latter third of the book, whereupon chaos breaks out. From this maelstrom emerges a conclusion which is both moving and remarkably bittersweet, despite the message of hope put forth in the epilogue. The book is certainly a quality piece of work, especially to those familiar with the previous trilogy and the first books of the series. When read together, this book helps to create a magical tour de force from Weiss and Hickman. I urge you to go out and buy the Legends trilogy, even over the chronicles. If only for the development of Raistlin and the acknolwedgment of shades of grey...
