For my science pick, I will take Mindhunter: Inside the FBI's Elite Serial Crime Unit, by John Douglas.
If you are into true crime books, behavioural and/or forensic science and the like, you'll appreciate this one. Douglas is the first criminal profiler in the FBI's history. He interviewed a number of the worlds most notorious and violent killers to understand their motivations, so he could put together profiles to help catch other criminals. In this book, he outlines several famous cases he worked on during his time with the FBI, what's involved with the science of profiling killers, etc. It's a pretty fascinating book, also, quite creepy looking into the minds of some of the most violent and terrifying people out there.
