Sure. I went ahead and updated the timeline I posted earlier below, to reflect Shadowhunter Academy.
The Shadowhunter Chronicles:
City of Heavenly Fire wrapped up the Mortal Instruments series. The next installment of the Chronicles is The Dark Artifices, which takes place five years after CoHF. You can read about them here.
There are three Dark Artifices books: Lady Midnight, Lord of Shadows, and Queen of Air and Darkness. Lady Midnight is tentatively scheduled for release in late 2015 though it is not definite yet.
The Last Hours, the sequel series to The Infernal Devices, begins publishing shortly after Lady Midnight. You can read about it here. It’s about the children of the Infernal Devices characters.
Tales from the Shadowhunter Academy is a sort of follow-up to the Bane Chronicles, in that it is 10 e-book stories that follow Simon from his arrival at the newly re-opened Academy in Idris for Shadowhunter training to the day he Ascends. You can read about it here.
So the order of books is:
The Bane Chronicles print edition, November 11, 2014
Tales from the Shadowhunter Academy, starting early 2015
Lady Midnight (The Dark Artifices 1)
Chain of Gold (The Last Hours 1)
Lord of Shadows (The Dark Artifices 2)
Chain of Iron (The Last Hours 2)
Queen of Air and Darkness (The Dark Artifices 3)
Chain of Thorns (The Last Hours 3)
That carries us through for quite a few years, so other than saying that the Shadowhunter Chronicles is intended to wrap up permanently with an installment called The Wicked Powers, I think that’s all I can say right now.
The Magisterium Series
The Iron Trial, the first book in the Magisterium series, came out September 9, 2014. There will be an installment of Magisterium every September for the next four years.
The second book, The Copper Gauntlet, is scheduled for September 2015.
Hope that helps!
