Leviathans of Jupiter by Ben Bova
The Sea Watch by Adrian Tchaikovsky
Deep State by Walter Jon Williams
Bitter Seeds by Ian Tregillis
Dark Inside by Jeyn Roberts
The Shining Girls by Lauren Beukes
The Books of the South by Glen Cook
Songs of the Earth by Elspeth Cooper
Snuff by Terry Pratchett
The Departure by Neal Asher
Most of these are books from series I've read or are planning to read and the prices for the hardcovers of Snuff and The Departure were just too good to pass up.
The limited edition of The Shining Girls by Lauren Beukes deserves a photo of its own. It's a gorgeous book with a stunning cover and finishes that slot in perfectly with the story itself. I'm very glad I opted for this over the standard edition. The story is great too; I finished it in one sitting, but so far I haven't found the words to do it justice in a review.
