Since this is a sticky - any passing mod able to edit the original post and add in the new publications? Would be good to keep the single first post updated not just have many comments below updating in bits.
Assassin's Fate is listed on Amazon as 7th March 2017 - quite a long gap for Robin Hobb to have between books (or I'm just having rose tinted glasses memories of her past pace at writing and publishing). A year later than planned, but likely going to be well worth the wait. The US listing even has some cover-art on show on Amazon.
