When Blaze is captured by giant birds, Tag and Skyla search the Cloud Kingdom for her, including the dangerous Silver Swamp, with only their magical map as a guide.

Now that Thorn has been defeated, Tag and his friend Skyla embark on a new quest, to find Blaze's lost family and the other firehawks who disappeared through a portal to the Cloud Kingdom; but the Cloud Kingdom is full of new dangers, and when giant birds seize Blaze and carry her off Tag and Skyla are left to try and free their friend--with only a magic map to guide them, and the threat of the shadowy shape that seems to be following them.

Tag the owl, Skyla the squirrel, and Blaze the young firehawk continue their hazardous journey to find and reunite the pieces of the Ember Stone, the only power which can defeat the evil vulture Thorn, and save Perodia.

Now that Tag and Skyla have found Blaze's firehawk family they would like to return home to Perodia, even if it means leaving their friend behind; but in order to find the magic that will open a new portal they must first brave a mysterious underground maze where the walls are constantly shifting--and when they do find their way home there is a deadly surprise waiting for them.
