Deep beneath Codaria lies a labyrinth of caverns where every path requires a decision. When Codaria's conditional system starts producing wrong answers - trains are leaving at the wrong times, shops are open when they should be closed, warnings don't trigger when they should - Maya, Leo, and Jaya dive into the Conditional Caverns to meet DECIDER, the ancient keeper of every if/else statement in the world. A paradox engine has been inserted into the decision-making core, causing contradictions that are slowly tearing Codaria's logic apart. To save the world, the children must master Boolean logic, AND/OR/NOT operators, truth tables, and the art of refactoring tangled conditionals into clean, readable code. Book four of the six-book Code Quest Chronicles. Ages 10-14. No screens required.
