Kitty paused a moment, considering that. "I...should be able to," she says after a moment. "It might be a bit tougher to open the books with the spines in the wall..." She gives it a try anyway, taking one book and turning it around to phase the spine into the wall, "and that does mean there will have to be a bit of space between the books so they can be opened...but it should be doable."

As she's trying to figure out the appropriate amount of space to put between each book, she glances back at him with his other question. "Not yet. I actually started here first."

She'd picked the library mostly to use as a proof of concept, just to see how well objects would stay when partially fused into the walls.
