Prologue
When the evil mermaid Mantora tried to destroy Coral Kingdom, she was outwitted by Misty and her young mermaid friends. Now she is hatching another terrible plot! This time it is against Ice Kingdom, the frozen realm of Princess Arctica.
Mantora has stolen six precious snow diamonds from the underwater Ice Cavern. Not only that, she has trapped Princess Arctica and her goodMerfolk in a huge cage of enchanted icicles, so they cannot follow her.
Unless the snow diamonds are quickly returned to the Ice Cavern, the whole of Ice Kingdom will be destroyed and the distant southern lands will be flooded with melted ice.
Only Princess Arcticaâs courageous young mermaidsâAmber, Katie, Megan, Jess, Becky, and Poppyâare small enough to slip through the jagged bars of Mantoraâs frosty cage. They are Sisters of the Sea, who are loyal to the Mermaid Pledge:
We promise that weâll take good care
     Of all sea creatures everywhere.
Weâll never hurt and never break,
Weâll always give and never take.
And as we fight Mantoraâs threat,
This saying we must not forget:
âIâll help you and youâll help me,
For we are Sisters of the Sea!â
Amber and her friends vow to find the snow diamonds, before their frosty home melts forever. They set off on their quest, taking with them only Princess Arcticaâs blessing and their stardust lockets.
Mantora has left behind a trail of cryptic clues about where she has hidden the diamonds. Can Amber and her friends solve Mantoraâs riddling rhymes and rescue the snow diamonds in time to save Ice Kingdom?
If you cannot find the diamonds,
The ice will start to melt.
On all sides of the ocean,
The danger will be felt.
No more will seals and polar bears
Enjoy their snowy home,
The seas will rise, the lands will floodâ
Storm Kingdom will have come!
So try to solve the riddling clues
Of Mantoraâs cruel game,
But if you fail to work them out,
The world wonât be the same â¦

Chapter One
âSo this is the Ice Cavern,â said Amber in an awed whisper. âIâve never been here before.â
She cautiously swished her sparkling lilac tail and swam into the middle of the underwater treasure store. Her young mermaid friendsâKatie, Megan, Jess, Becky, and Poppyâfollowed her eagerly. They gazed up at the shining walls of icethat arched above them in a cluster of glistening icicles.
âItâs so beautiful.â Becky sighed, glancing around with wide eyes at the carved walls. They gleamed with frosty flickers of white and blue and turquoise.
It was the first time the young mermaids had seen the secret Ice Cavern, where the snow diamonds were kept. The diamonds were full of magical power, which helped Mother Nature keep Ice Kingdom frozen.
âWow,â said Poppy as she swam slowly around the magical chamber. âLook at those!â
Amber and her friends stared in wonder at the six fabulous frozen statues that stood around the cavern. There was a darting fish, a flying bird, a glowing heart, a diving dolphin, a flowerlike anemone, and a shimmering star. The mermaids wove in and out of the statues, through the clear, cold water.
âHave you noticed that the statues are the same shapes as our new stardust lockets?â asked Amber, stretching out her arm gracefully. A silver bracelet shined onher wrist, and from the bracelet dangled a sparkling locket, carved in the shape of a leaping fish.
âYouâre right,â agreed Jess. âLook, Iâve got the dolphin on my bracelet.â
One by one, the mermaids raised their arms to admire their shining stardust lockets.
âMy locket is in the shape of the seabird,â said Katie. She examined her bracelet happily, then looked up at the matching ice carving.
âAnd mine is the anemone, which is like a flower in the sea,â murmured Becky dreamily. âWhat is yours, Megan?â
âOh,
