It's actually kind of surprising that these books exist, at least in their current form.
The original Dragonlance Chronicles was the trilogy that launched a thousand other D&D tie-in novels; a wildly successful story in which the Forces of Evil were pitted against a half-elf, a dwarf, a Hobbitkender, a knight, a plainsman and a cleric. Oh, yes, and a fighter and his sickly twin brother mage. And there were epic journeys and dangers and setbacks, and a few tragic deaths, but in the end the aforementioned Forces of Evil were, in fact, defeated.
And the follow-up trilogy took just about all of those elements and threw them right out the window, opting for a much more personal, much darker story.
The time: A few years after the end of the War of the Lance. Although we begin with a reunion by all of the (surviving) heroes from the first trilogy, the focus shifts to a much smaller subset: the sickly mage Raistlin Majere, who, by the end of the first trilogy, had cast his lot with the powers of darkness even as he helped the others defeat the powers of evil; his twin brother Caramon; the cleric Crysiana, a new character who thinks she can redeem Raistlin (and also he makes her feel all fluttery, although she's not necessarily ready to admit that even to herself); and, of course, the irrepressible/irritating kender Tasslehoff Burrfoot, who continues in his role of kleptomaniac comic relief and occasional conscience.
The years have not been kind to Caramon -- yes, he's now married to Tika, his sweetheart from the first trilogy, but he's also (not to put too fine a point on it) a fat drunkard driven to despair at the thought of his brother's fall from grace. But through circumstances he finds himself, together with Tasslehoff and Crysiana, traveling back through time to the city of Istar a thousand years past, in order to foil his brother's schemes.
Remember Istar? The city that, in the original trilogy, is best known for getting smacked by the gods with a meteor or something because its Priestking got entirely too full of himself? Yes, that Istar. And time is growing short ...
This is a difficult one to rate -- considered purely from a story perspective, it's much better & more interesting than the original trilogy (which, to be sure, I enjoyed). But (as with the original trilogy) the actual prose is, um ... not great. To the point where there were times when if I'd had a red editor's pen, I would've been scribbling all over my Kindle. So it's just as well that I didn't have such a pen.
And in the end I'm going with four stars because however painful I might find some of the sentences, I read the book in basically two or three sittings and will be moving immediately to the next in the trilogy.
