The Gollancz sales items can be seen at Amazon UK with
this link
I'd like to highlight the following, which I greatly enjoyed:
The Final Empire by Brandon Sanderson
The Lies of Locke Lamora by Scott Lynch
Rivers of London by Ben Aaronovich.
Three wonderful fantasies, each the start of an excellent series.
If anyone has any particular recommendations from the Gollancz sale, please mention them
