[Abhorsen #4] Technically a prequel but it’s book four in the series.
Legacy of the Claw [Animas #1]
Waistcoats and Weaponry [Finishing School #3]
The third in Gail Carriger’s Finishing School Quartet (final book out November 2015).
The ten Magnus Bane (of Infernal Devices trilogy and Mortal Instruments series fame) stories previously only available as ebooks, in physical book form!
There isn’t anything I know of yet, releasing in December that I’m excited about.
