Obscura is a sci-fi/thriller hybrid about a medical researcher in space. That was a setup I’d never heard before! I love when a book feels like a fresh and original experience.
Gillian Ryan is an expert on a dementia-like disease that can affect people of any age. She lost her husband to it, and now her daughter is showing signs as well. When she is approached by NASA about going into space to see if she can help astronauts who have been showing similar symptoms, she agrees because she hopes doing so will help find a cure to save her daughter.
There are a few problems: One, Gillian has an addiction that clouds her judgment and, at times, her perception, and two, NASA lied to her about key aspects of the mission. (Like, really really important aspects.) And that, my friends, is a recipe for a space disaster if I ever heard one!
While I got a little annoyed from time to time (I don’t like being inside a character’s head while they’re on drugs, for one thing, it’s just not my bag), mostly I was engaged with trying to put the pieces together to figure out what the heck was going on and how Gillian was going to get out of a string of impossible situations. This would be a fun thriller for your beach bag.
