If you an avid reader you probably tend to meet others who love to read too. And then you start sharing book recommendations. The issue for me was two fold. It was hard to recall the right titles, and then a hassle to write down recommendations on a napkin.
For recommendations I know use my book project jot down who gave it to me and book name. I found the actively doing that excites the give and get you more recommendations. Fun for us reading nerds.
Cecily is one of my best recommenders and this is one of her best recommendations:
Cecily: Wind Up Bird Chronicles
https://www.amazon.com/Wind-Up-Bird-Chronicle-Novel/dp/0679775439I tend to use one message per recommendation.
