Their magical map is leading Tag, Skyla, and Blaze closer and closer to The Shadowlands, Thorn's territory--but now the Ember Stone has fallen into the well-named Lullaby Lake, which is defended by fairies who sing intruders to sleep, and the friends must figure out a way to convince the "nixies" to help them retrieve it before Thorn gets his claws on it.

Tag the owl, Skyla the squirrel, and Blaze the firehawk are searching for the final piece of the magical Ember Stone that will hopefully save Perodia from the evil vulture Thorn, and their quest has led them to the Howling Caves in Valor Wood--but they do not know if the stone will actually be there, or what will be waiting for them when they emerge into the spreading darkness.

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.
