Every issue, SFX teams up with WHSmith to offer you a discount on a key new SF/fantasy book.
This month's title is the new novel by Iain M Banks: The Hydrogen Sonata . His latest Culture book, it finally reveals what "Subliming" actually is, and concerns what happens when a society ascends.
Simply cut out the voucher in SFX issue 227 (you'll find it in the book reviews section) and present it in your local high street WHSmith to get the book for half price - that's £10 instead of the RRP of £20.
What's more, if you buy the book in WHSmith you get a special limited edition with an alternate cover design!
Please note: the book is released on 4 October, and the voucher is valid from 4 October to 16 October 2012.
Remember, you can also meet Iain M Banks on 11 October in Manchester if you enter this competition !
