Book Three: Cult of the Conductor

Grace and Simon look on the bright side and hope that this will be like a mini-vacation from their responsibilities as leaders of The Apex.

The gang's uneasy alliance is tested by a challenge in their first car together: dancing in a high-stakes octopus debutante ball!

Stuck in a blizzard, the gang seeks shelter in a nearby cabin. But when Simon realizes who's inside, he frantically searches for a way out.

A giant, color-changing clock creates a shifting-maze puzzle that the gang has to solve before they can leave the car.

The Apex are just a car away! They're almost home! But first they have to make it through a forest full of pinecone camp counselors.

The gang finds themselves in a car full of golden winged snakes, but in that dusty landscape a mystery they're unprepared for awaits them.

In the seemingly innocent Hey Ho Whoa car, a shocking revelation rocks Grace and Simon's world. Will they be able to fix it before The Apex find out?

The gang is finally ready to meet The Apex again, but keeping secrets has consequences.

The gang reorders The Apex, but what will the new order be?
