This is a series by Zaffie. It takes place probably 20 - 25 years in the future of the Mortal Instruments.
In terms of reading, there are two potential orders for the series. The first is the order in which the stories were written, and the second is chronological order, in terms of the time the stories took place. I'd reccommend reading in chronological order, but it's up to you.
Lux Altum - Coming Soon
Lux Amissa - Coming Soon
Lux Invenit - Coming Soon
Lux Gravem - Coming Soon
Lux Excaecatio - Coming Soon
Lux Daemonum - Coming Soon
Lux Aeterna - Coming Soon
