It has been decided that the re-release of Solstice will release on Kindle at $0.99! Not only that but it will be put on Kindle Unlimited as well. The paperback edition is projected at costing $9.99 currently, but I will update everyone when that is set in stone.
I feel that this is a good price to get people in on the action early. At this point, the sequels will come out each month afterwards, Equinox in October, Ecliptic in November, and Celestial in December.
Preorders will happen soon, so keep an ear out.
