Made in Blood
Mars Adler

Everything goes to plan until Julian wakes in a strange part of the base with even stranger plants, three days missing from his memory and food supply, and Callum acting erratic and feverish. Roy is convinced that there's something horrible happening, and that Callum somehow caused it.
Torn between loyalty to his friend and keeping his son safe at all costs, Julian has to figure out what's wrong with this place, why Callum is acting the way he is, and how he can keep the peace between all three of them.
But there's something hungry and wrong in this abandoned base, something that's changing the world around them, and changing them. They're running out of time to figure out what happened to those who came before, and escape this place with its weird, mutating plants that distort how he feels about his son. Just how far is he willing to go to save Callum?
