Over on my personal blog I re-read and then wrote a review of each book in the Winter of the World series.
Book 1 – The Anvil of Ice
Book 2 – The Forge In The Forest
Book 3 – The Hammer of the Sun
Book 4 – The Castle of the Winds
Book 5 – The Singer and the Sea
Book 6 – The Shadow Of The Seer
It’s a 6 book series by Michael Scott Rohan which varies in quality and how they connect to each other. I’d recommend giving the first one a go anyway and decide what to read after that.
As well as being an Ice-Age era fantasy series there is also a Tabletop RPG and Map available. I’ll probably pick these up for the short stories and fluff included if nothing else.
