For those who have never heard of it before, Booktube refers to Youtube channels where books are reviewed, discussed and talked about. I have discovered it just recently, and I find it addictive
The first booktuber I had discovered was Sasha from Abooktopia, and I really loved her videos.
My other favorite booktubers (in no particular order), include:
Benjamin from Benjaminoftomes
Kat from Katytastic
Regan from Peruseproject
Jesse from Jessethereader
Christine from Polandbananasbooks
