Not normally a scifi reader but I saw the book recommended on a few blogs Halloween scary reads recs last year so I got it from iBooks.
Started off kind of slow, but interesting enough even with NASA and space jargon to keep going and a few unsettling incidents happening to the teens before they arrived together.
Once they got too the Moon was when the plot really picked up. Not going into details as it would be really spoilery but it got almost claustrophobic and intensely freaky.
Left at an extremely unsettling ending. I'm a horror fan but not much freaks me out anymore but this book was out if my comfort zone and left
me with a chill.
Highly recommended for at atmospheric horror with a difference.
