From the description:
"Bears, princes, witches, dwarves, and other fanciful fairy tale creatures step out in this charming story about Annie and her sister Gwendolyn ... and Gwendolyn’s beloved prince, Beldegard the Bear. You see, Beldegard is only human when he’s near Annie, so Gwendolyn is desperate to find the evil dwarf who turned Beldegard into a bear in the first place, and reverse the terrible spell. But Annie has just traipsed all over the kingdom to free her sister from the Sleeping Beauty spell...will she want to set out on a magical quest once more? Or has she had enough of watching her sister gaze lovingly into Beldegard’s eyes?"
