The Anvil of Ice, The Forge in the Forest, The Hammer of the Sun, by Michael Scott Rohan. Collectively the Winter of the World trilogy. I love these books.
How to describe them... ah, the writing isn't brilliant, from a prose point of view, but it's workable and more than readable. The characterisation is nothing special, although the source material gives it an edge. The setting is both original and unoriginal - essentially it's three books worth of "spot the North European myth" set around the last glacial maximum with a somewhat unusual twist given to normal fantasy standards. That he pinches so many myths is unoriginal; that he weaves them together so perfectly is why these books are among my very favourite fantasy novels. The plotting is very tight (this ain't no TV scriptwriter - yes, looking at you, GRRM - style "let's throw a hundred plot hooks out and randomly pick up on a few of them but not actually have a plan", it's not even a LotR write-and-rewrite thing, this is a meticulously planned trilogy with everything in the right place; a second read-through will be rewarding on account) and it all leads up to an excellent take on one of the nastier myths from the Scandinavian canon and the single most outrageous/spectacular/funny scene I've ever read in high fantasy.
(As an aside, both this and the same author's Spiral books suffer from being very hard to describe the plot with giving away enormous spoilers - it's like "the hero REDACTED travels to REDACTED and meets REDACTED where they REDACTED with the REDACTED" if you try!)
It's a crying shame that they're out of print, but that also means you've little excuse for not picking up a copy at £0.01 + P&P on t'internet. Especially if you like Norse myths and/or the Kalevala.
Also read Jesus on ThyFace: Social Networking for the Modern Messiah - social networking was big back then, and the book is a collection of excerpts from Our Lord's ThyFace pages. A bit hit-and-miss, but some laugh-out-loud funny bits.
Got a bunch of Hornblowers lined up, and the three non-sequels to the Winter of the World trilogy.
