One of my favorite science fiction authors, J. Grace Pennington, has just released the newest volume of her YA sci-fi series Firmament. Reversal Zone is book four in the series. Firmament, like Star Trek, follows the adventures of the crew of a starship, but from the perspective of a starship nurse instead of the captain.
Although I’ll be ordering a paperback of Reversal Zone since I prefer print books, I thought I’d mention that the whole Firmament series is free to read digitally on Kindle Unlimited. Anyone who has Kindle Unlimited and likes sci-fi should definitely give Firmament a try. The series is best read from the beginning, though any of the books can also be read on its own.
