I own 5k+ books so I may be a little biased but this is really good anime.
If you are looking for light warm heated fluff and about the importance and family and pursuing a dream, this one is for you.
The characters are unbelievably cute and enjoyable.
Myne the main character is highly relatable, and a welcome change from the usual isekai blockheads. The only cheat she has is the memories of her past life, and it's far more accurate to say she has enough detriments to crush a busload of high schoolers summoned to another world. She isn't perfect, she isn't infallible but she manages. A really nice character to see.
Lutz, her love interest is nobody's fool, least of all hers and it's nice to see that too. He's obviously in love with her, and the anime doesn't go stupid on you with their romance. Thumbs up again.
Her family is equally well done. A wonderful family who's only problem is they are a little too good.
The plot is an enjoyable overview of Myne doing whatever she can to live a life surrounded by books. It's for the most part believable, though I wouldn't advise looking up how to make anything she brings from the modern world. What's more the plot actually manages to end well in the 14 episodes the anime runs for. From my point of view and opinion about reading material, it was a really unhappy ending, but YMMV.
TL:DR watch and enjoy
