Really, this should be called The Orbital Drop because that's where I'm getting these deals.
Blood of Elves by Andrzej Sapkowski ($2.99) - I wasn't a huge fan of The Last Wish (It's an early review, don't judge me) although I thought it was mostly due to the translation, the dialogue was just odd.
For Today Only:
The Dragon's Path by Daniel Abraham ($2.99) - Includes Hugo Nominated Leviathan Wakes as well.
EDIT: Non-Orbit deals
Ship Breaker by Paolo Bacigalupi ($2.99)
Servant of the Underworld by Aliette de Boddard ($2.99)
