Card	Type	Ruling
Book of Life	Individual Card FAQs	If you activate "Book of Life" and your opponent chains "Call of the Haunted" to Special Summon "Kycoo the Ghost Destroyer", you still get to Special Summon 1 Zombie with Book of Life's effect (but do not remove 1 monster from your opponent's Graveyard).
Book of Moon	Individual Card FAQs	When you activate "Book of Moon" during the Battle Step to flip an attacking monster into face-down Defense Position, the attack stops. No replay is triggered. The attacking monster cannot change its battle position in Main Phase 2, because it is still considered to have declared an attack. (So it cannot be Flip Summoned in Main Phase 2.)
Book of Moon	Individual Card FAQs	If you are attacking, and you chain "Book of Moon" to your opponent's "Mirror Force" to flip one of your monsters face-down, that monster is not destroyed by "Mirror Force".
Book of Moon	Individual Card FAQs	If you chain "Book of Moon" to "Magic Cylinder", "Ring of Destruction", or "Trap Hole" to flip the target of any of those cards face-down, the card's effect disappears. (See "Activation & Targeting Eligibility" in the Advanced FAQ.)
Book of Moon	Individual Card FAQs	When you activate "Book of Moon" during the Battle Step to flip your defending monster into face-down Defense Position, the attack resolves as normal. No replay occurs because the possible attack targets on your side of the field did not change.
