H.P. Lovecraft - Necronomicon. Its just a fat collection of a lot of his stories. Really enjoying it and its a cool looking book.
I'm just about to finish the Lovecraft Omnibus 1 'At The Mountains of Madness'. I'd only read some of his stuff online before this and I'm really enjoying it too. Omnibus 2 is sat on my shelf waiting.
I'm also simultaneously re-re-re-reading 'Look to Windward' by Iain M Banks. Has to be one of my favourite all-time books and the cream of the culture series.
