Just found this post. Glad to see it's still up here.
I've listened to a load of audio books recently due to doing a lot of driving. I can strongly recommend:
Columbus Day - Craig Alanson
The Cuckoo's Calling (and others in the series) - Robert Galbraith/JK
American Gods - Neil Gaiman
Tom Wood's 'Victor the Assassin' books.
There's a lot more I could add, but these will do for now.
The 'Cuckoo's Calling' is the first book of a trilogy, I have just finished the 3rd book 'Career of Evil' all 3 are excellent reads.
Also it looks like the BBC are making a TV series of all 3 books, yes I know TV and films never give the book justice but they have 'Tom Burke' playing the lead character and if JK gets to give any input to the production it might be half decent.
