"Throws book at" is a phrase used to describe an action of imposing severe punishment or penalty. However, there are several antonyms that can be used to describe a less harsh action. Instead of throwing the book at someone, one could forgive them, show leniency, pardon or even show compassion. By showing mercy, one could also offer a warning, reprimand or a more minor punishment as opposed to a full-scale disciplinary action. These alternatives would take into account the situation and the individual involved and could ultimately lead to a more positive outcome.
