Nightflyers (Novella) by george rr martin review

So I got this book from one of my friends as a secret Santa present and all I knew was that it is a SCIFI Horror novella so I'm like why dont i read this now. I read the whole thing in one night and i have to say its unlike anything I've ever read. The story is that this space team have come aboard the space ship known as the nightflyer and what they are doing is is that they are going to try and find a alien race. That's all until they start getting killed one by one by a mysterious entity. This is one of the most suspenseful and scariest sci fi books I've read and the ending is actually quite nice and happy. I highly suggest this book if your a george rr martin fan and from my research I've done I've found that this book was adapted into a 1987 horror film and a 2018 TV series which was just recently cancelled only after one season.
