I recently finished And Then There Were None, a thriller by Agatha Christie. I haven't read an Agatha Christie book in ages, but I picked it up on the recommendation of Anne Bogel from Modern Mrs Darcy in one of her "What Should I Read Next" podcast episodes. Her son also read the book and said it was the best book he ever read, which intrigued me to see what about this book could cause a teenager to love it. I ended up agreeing it is great too. What a baffling mystery and chilling thriller!
I just finished this book called Dark Matter by Blake Crouch, and it is mind-blowing. I'll avoid spoilers, so you can enjoy it yourself, but basically, it's a story of a college physics professor who gets abducted one night, taken to an abandoned location and drugged. When he wakes up, he finds himself in a different world where he's a genius atomic physicist living a successful but career-oriented life, his wife never married him and his son was never born.
'Mockingjay - Part 2' follows the book pretty much faithfully -- except for all the subtext that they could not (dare not?) translate to screen, which Darren Franich from Entertainment Weekly explains in a brilliant analysis.
