It is such a wonderful family there and everyone is so inviting and encouraging. All you have to do is have an interest in reading. A lot of the channels focus on YA or teen books, but there are quite a few that delve into other categories as well. Me personally it's a mish-mash. Lately it has been a lot of YA/dystopian type books but I read just about anything.
If you are interested in seeing what the BookTube community is about, I have linked some of my videos below as well as a link to my channel above. I'd love for you to come check it out and also just search for some more on YouTube. You won't be disappointed.
Plus, I think it's a great way to get younger people to read because it combines technology with books, and shows people their own age getting such joy out of what they are reading.
