Behold a super-satured solution. A crystal touches it and where before was a liquid, now hard unyielding crystals spring forward, hard enough to scratch diamond. Some books are seed crystals, changing the shapeless into eternal forms.

Let me know when you find such a book ;-)

All books can be seed crystals, provided they find an appropriate super saturated solution in their readers (that was my point, actually, as a counter argument to OP's "preaching to the choir". Although the super saturated solution is already there, it needs to seed crystal to (physically) transform).
