Silky and the Everlasting Candle by Enid Blyton
Picking up where the hugely successful "Faraway Tree" series left off, the inhabitants of the Enchanted Wood face the biggest threat to their existence yet - the death of the Faraway tree! Silky and the Everlasting Candle: It's party time in the Land of Birthdays! Imagine a place where your wildest birthday dreams can come true. The Faraway fairies, however, are on a mission. They need to find the Land's Talisman, the Everlasting Candle, and return it to the Tree before Talon the Troll can snuff out their plan.
