"resets unit's ability charge" - this sounds like a negative? which appears to be on all the books, making books seem less desirable than cards. 

Am I right with that assessment, or am I misunderstanding something?

That's correct, it is a downside. However, you gain more stats with books than cards, so if you can afford less dps, books are better

(+1)

So I actually have a question about that... isn't it actually an upside? If you put the book on a damage dealer, you take longer to kill the enemies => you have more time to gain stats => you become way stronger

And in a boss fight you just remove the book and enjoy the carnage.

This person has discovered the forbidden tech :O .

But for real, yeah, it's a great strategy! Just be careful to not farm stats for too long during fights since the enemies start exponentially gaining POW the longer the fight goes on.
