Really compelling and eerie read. The author is great at slow build ups, but sometimes the execution for the climax isn’t the best. I think one of the reveals definitely could’ve been tweaked to make it feel a little more real. Halley was a fine protagonist to follow, but what really was great was how she interacted with the setting, especially with sleep deprivation and isolation messing with her head. I appreciated the message that the book is conveying, even if you can’t change the world, doing something is better than doing nothing.
