Bend Your Brain: 151 Puzzles, Tips, and Tricks to Blow (and Grow) Your Mind - Lindsay Gaskins
This is a fun book. Trying to work out the puzzles was a blast when they hubby and I started competing to do it. Many of those puzzles aren't easy, and we had to work together on a few. This is perfect for people who like to do puzzles. We are big fans of the show Brain Games, and this reminded us both of that show but something more accessible to us.
