Butterfly Magic II

Butterfly Magic II is a children's Christmas fantasy set on the Central Coast of New South Wales on the east coast of Australia, where Christmas happens during the hot, sunny days of summer.
Events are triggered when a prank is played by one of three volunteer firefighters acting as Santa's elves. While escorting Santa to a village Christmas party, the prankster spies a scarecrow on a front lawn. He pulls the scarecrow out of the ground, placing it next to Santa on the fire truck.
They then travel to the Christmas party. But at the end of the day, the "elf" forgets to return the scarecrow, which is when the trouble begins. The scarecrow's owners demand its return and threaten retribution.
They abduct Jack, the grandson of one of the elves. Jack is taken to a small island off the coast of New South Wales and is caged inside a cave.
In his prison, Jack is visited by a witch, a serpent, and magical monarch butterflies.
This second book of a series features Rebecca, Fredericka, and Jack, children from the first book.
