This book was written 20 years after The Lion The Witch & The Wardrobe, and 14 years after The Last Battle. You can almost map the influence. Travel to alternate realms happens by falling in while the local Pan-god plays his flute. Good and Evil are having their Last Battle, because good is losing very badly. In the end, Major Female Character loses her magic because she fell in love – she’s a princess, though, not a queen like Susan. And in the end everyone goes home and it’s like nothing ever happened.
Interesting variation: They need a ‘son of Adam’ because Big Bad Guy can’t be killed by anyone born on-planet, and someone with blue (death-color) eyes will signal his death. The older boy falls into fairyland back in time and far from the other two, and magic makes him forget himself while training to be a warrior. His name Young Tiger is also part of the prophecy, and a tie-in to the tribe’s prodigal son.
