Lyra, Obsidian, and Xara stopped Zara. But she left a very big problem in her wake before she disappeared into Eloh. Zara had stolen the solid drop of light that fuels the Sun, and without it, the Sun will go dark and the Earth will slowly wilt. It is up to Lyra and her friends to replace it. However, that is hard to do when the adults tell you that you can't help them! Join them as they team up with Lyra's mentor and uncover weird family history, meet many new friends, and maybe even succeed in their mission!
