The Odyssey

When 11-year-old Jay Ziegler falls from a treefort after being pursued by bullies who wanted his father's precious telescope, he ends up in a coma - in the real world (known as the Upworld). In the Upworld, Jay's mother Val, his best friend Donna and the bully Keith all try to cope with their reality. In the Downworld (Jay's mind), Jay finds himself in a world entirely populated by children, where he meets up Alpha and Flash (the Downworld counterparts of Donna and Keith) and the trio embark on a mysterious mission involving a telescope, the land's mysterious leader Brad, and a connection to Jay's father.

In the Upworld, Jay's coma worsens and he's taken to intensive care, causing Val to be faced with the prospect that her son may never recover. Meanwhile in the Downworld, Jay believes that his connection to home lies in the Tower, so he sets out with his companions to find it.

In the Upworld, Jay's condition becomes more stabile and his classmates make him get-well-soon cards. Meanwhile, in the Downworld, as Jay and Alpha prepare for re-education at the mission, Flash recruits some tower-resistance fighters to help rescue the pair.

In the Upworld, Val moves Jay to an experimental private care facility called Driftwood, where she meets Dr. Max Oswald who has developed some experimental treatments. Meanwhile in the Downworld, the trio make their way to the library club where they can get a map to the tower.

In the Upworld, when Jay's paternal grandmother isn't up to the task of helping Val with Jay's physiotherapy, Val allows Donna & Keith to help in Jay's recovery. Meanwhile in the Downworld, Jay, Alpha and Flash find the first of three checkpoints but have to face tests to get through them.

In the Upworld, when Val is laid off work due to her spending so much time with comatose Jay, she decides to visit her mother in the country at the family farm. At Driftwood, Donna and Keith continue to help by reading King Arthur stories to Jay. Meanwhile in the Downworld, the trio reach a cornfield where Flash meets Lobelia & Yudo and learn of Yudo's belief of ""Big People"".
