My Sister, the Serial Killer - Oyinkan Braithwaite

 I thought this was a pretty good book. The author does a great job in keeping the pace, jumping between dates for the "memory scenes", and making the MC feel real.  That last one was the best.  The MC keeps helping her sister cover up her crimes, even though she hates it and wants out.  Any outside advise would obviously be: simply stop and leave her to clean up her own messes.  But the author does a great and honest job of showing the MC's motivation even in the event of her crush being on the chopping block. This is an intense, wild ride and I would recommend it for any of my crime story loving friends. 

The Secret Life of the Mind: How your Brain Thinks, Feels, and Decides - Mariano Sigman

 This is a super fascinating book covering a wide range of brain-related phenomena that I’d not learned of before. If you want to know all the details, read the book, but I will leave you with an example: Every time you move your eyes, your brain shuts off.  Just try it. Look at something to your right and then look at something to your left.  You can see in your peripheral but the details of your eyes tracking across everything in the middle aren't there.  It will annoy you forever now. You're welcome.
