Author volrathxp is having Fallout Equestria: Starlight printed as a series of four volumes. Orders will however only be open to patrons/donors. There currently appear to be three ways to get hold of the books:

• Support the author on Patreon before 15 April for a chance at a free copy of volume 1 (and also be eligible to buy volumes 2–4).
• Higher level patrons will be eligible to buy copies for the cost of printing and shipping.
• For those who do not want to sign up with Patreon there's also the option of making a one-time donation.

There's also the possibility of a larger print run as long as someone else is willing to do all the work.
