At the stroke of midnight on the dawn of December, five-year-old Finn Albedo is found frozen in the city park standing on a pedestal of ice. His heart is beating, he is smiling serenely, but no one can wake him.

Finn’s big sister, Bianca, suspects that the beautiful sparkling book Finn got from the library has something to do with it, but the book has vanished. Does the tall mysterious stranger who first discovered Finn know more than they will admit?

Each day, more children are found frozen and Bianca realizes she’s running out of time. Her quest to discover the truth and rescue her little brother hurls her into a fantastical winter wonderland, full of beauty and danger, where all is not as it seems.

Can Bianca save her brother and the other Ice Children before they are forever lost?
