I'm glad you liked the series, it really is a good one!
I finished watching The Bay (2 seasons, 6 episodes each) and I really liked it. Now I think I'm going to take a small break and continue reading Sharp Objects and then I will watch The Act or The Undoing. Nicole was amazing in Big Little Lies, I was surprised how well she did that role so I'm looking forward to watch her again.
You definitely can't go wrong with Donato Carissi! :D I am obsessed with his books, they are so intense and mysterious. Also if you ever find a book called Rodjen da ubije, I would highly recommend. I guess I should read the book you got as enthusiasm might be something I am also lacking, haha. I'll look for it in PDF as I don't think my local library has it. :)
I am the same when it comes to spending an entire day watching the series or reading a book, that's why mini series are perfect for us. :D
When you finish the book, let me know what you think about it and if it was helpful, maybe I could borrow it from you. :)
I'll watch the trailer now. :D
