Baron von Bubbles (Bub) is a pug who wants nothing more than to help his human Bella in her craft projects for school, though he is a little apprehensive about the rocket she is making for the Inventor Challenge--so when he ruins the rocket while trying to get at Nutz the squirrel he needs to find a way to make it up to Bella.

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.

A famous author is coming to visit and Eva Wingdale and her classmates are assigned to write a story--but Eva is totally distracted because her pet bat, Baxter, has gone missing, and she suspects that the sneaky squirrels have something to do with her missing pet.

Tag and Skyla have returned to Perodia to begin their warrior training, but when their friend Blaze returns with troubling news that her mother has gone missing, Tag and Skyla's warrior skills are quickly put to the test.

Tag, Skyla, and Blaze are on a new quest to find Blaze's family, and Thorn's twin brother, Claw (who claims to be nothing like his evil brother), has offered to guide them to the mysterious Golden Temple where the firehawks were last seen; but the jungle is full of dangers and Tag is not sure they can trust Claw.

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.
