No, you can't do something similar to Macaulay Culkin's experience in the movie, The Pagemaster .
Magick is just a form of science that has yet to be rationally explained. Throughout history, Magick was right up alongside science until the Church and other rulers at the time decided to outcast it to hoard the secrets and learning for themselves in order to better maintain their power and keep the people subjugated.
Thus, you can't break the laws of physics and other natural laws.
Moving your physical body into a material object is not possible. Stop and think about what you're really looking for. You're not after being inside a book . You're after being more immersed into the story . Those are two entirely different concepts.
Understanding subtleties are important, for a number of facets in life.
Now, greater immersion in a story is entirely possible with principles you learn through the basics of magick. Visualization is important in magick. Through visualization you can create thoughtforms, places in the Astral, etc. In fact, visualization enables you to do quite a lot in pressing your Will into reality.
Think about this for a minute.
If you are imagining the entire world, scenes, scents, people, and other elements of a story that the author's words depict, you're effectively creating your own little addition to the Astral, however temporary. The more you work at Visualization, the more cemented that addition is. This is a similar concept to creating an Astral Sanctum or Temple.
Look into this. It's as close as you'll get to fully imersing yourself into a story. Only it'll be at the Astral level, not the physical one.
