The critically acclaimed, best-selling middle grade series returns with an all-new, sci-fi DIY adventure!

Celine and Tuck's parents put them to sleep for centuries to ride out the energy crisis — but when they awake in the far future and Mom and Dad are missing, it's the kids who have to save the day! Celine and Tuck must explore a strange, new Earth using their gadgeteering skills to create projects and experiments to survive hostile tribes and bizarre mechanized threats — projects and experiments kids and parents can make themselves at home, and learn basic energy literacy at the same time!

Collects HowToons: [Re]Ignition #1-5, along with backup strips/projects by series originators Nick Dragotta and MacArthur 'Genius' Grant winner Saul Griffith.
