The attack will go through. The last act was the declaration of the attack. True the completion of the attack (gameplay) is interupted by the activation of enemy controller, but if at the end of the resolution of these effects, the card is still in attack position on your side of the field (Final Atttack Orders), it will go through upon return to gameplay (provided nothing was played that would actually STOP the attack).

Book of Moon puts the card in f/d defense, so in that case the attack stops because Final Attack Orders only affects face-up monsters.
