Phraseology for book worms

Is there a concise phraseology for when somebody dives their nose evermore into books until the book eats them whole? Sort of like the lesson telling that you can sometimes be too well-read in life.

You can eat, drink and laugh yourself silly, and in a similar way people have been said to read themselves silly.

In the old days they would have said of him that he read himself silly. His overstimulated intellectual activity was too much for the strength of his frail organism. (My Past and Thoughts: Memoirs of Alexander Herzen, Vol 3, p280)

Morton, you remember me telling you about a boy what read himself silly? This is him, and blamed if he ain't read himself blind as well. (Stiffs, Melbourne Garahan, p154)

Probably the most idiomatic expression for being absorbed by a book (rather than being generally addicted to reading) is She buried herself in her book.

bury [oneself] in

...

• To immerse oneself in a task or project. In this usage, a reflexive pronoun is used between "bury" and "in."
  • Ever since my breakup with Ben, I've tried to bury myself in my work to keep from crying all day long.
  • You will need to bury yourself in your schoolwork to get a passing grade this semester.

[Farlex Dictionary of Idioms]

An example using 'in one's book' as the prepositional phrase from a credible source is:

• ... but the Doctor's face was too awful; Tom wouldn't have met his eye for all he was worth, and buried himself in his book again.

[Tom Brown's School Days; Thomas Hughes]

'Burying oneself in one's books' and variants, for the overly bookish, would work too.

'Overly bookish' is accurate, but very dry.
