Our book group finds regularly that when we all enjoy the book, discussion can sometimes fizzle out as we run out of things to say! Not the case with Hamnet though, we were all very glad we had read it and (in some cases) persevered even when it became emotionally draining.
Sometimes my heart sinks at a book choice though, there are “fashionable” books which apparently “everybody is reading”, often first novels which frankly I can do without. I will give most things a try, but if I am not engaged by about page 100, or if it is clunkily written, I have no compunction about giving up. Life is too short and I have too many books on my BTR (books to read) pile.
