The Gadget Sandbox Chronicles

A complete six-book building adventure for readers 8 to 12. Captain Cubemelon and his friends link six worlds, one gadget at a time, with teamwork and clever thinking instead of fighting. No cliffhangers-forever, no waiting for the next one. Start with The First Build (Book 1).

The First Build (The Gadget Sandbox Chronicles, #1)

Place the crate. Aim the fan. Open the portal. What could go wrong?

Captain Cubemelon thought the first build would be easy. Set the spring pad. Press the button. Save the scene. But when Pip Pop bounces through an unfinished portal before the team can lock the build, the first test becomes the first rescue.

The Mech Workshop Machine (The Gadget Sandbox Chronicles, #5)

Some flowers are load-bearing. The workshop forgot.

Mech Workshop is a paradise of gears, cranes, conveyors, pistons, and magnets. Patch Bolt calls it beautiful because it works. Brick Bloom calls it unfinished because it has no joy.

Portal Park (The Gadget Sandbox Chronicles, #6)

Some doors are paths. Some doors are questions. Some doors are closed because opening them connects more than you are ready to hold.

Portal Park is a maze that laughs at maps. One gate leads to the snack path. The snack path leads back to the first gate. A purple door sends Ember to a blue bridge. A blue bridge sends Pip to a sign that says he is...
