101 missions. Four levels. One 24-hour boss fight.

An activity book for 12–16-year-olds, built like a game.

Every mission earns XP. Every level unlocks a new rank, from Rookie to Offline Legend. And at the end, a 24-hour offline boss challenge with a certificate for whoever survives it.

Inside: three self-working card tricks, five knots, three-ball juggling, Caesar and pigpen ciphers, touch-typing, the Italian Game chess opening, cup stacking, a wall handstand, three breakfasts cooked from scratch — plus squad missions that pull in siblings, friends and unsuspecting grandparents.

Every page has space to write, draw, log or track. It's a book that ends up filled in.

What it isn't: a lecture. Not one page says screens are bad. It just makes real life look more interesting.

149 pages, black and white, with instructional diagrams throughout — including restored public-domain plates from Victorian manuals on hand shadows, conjuring and ropework.
