What's inside
The book opens with a cover and a one-page statement of the rules — two stars in every row, column and outlined region, no two stars touching — then the boards, four to an A4 page, sized for a pencil. Every board is Medium tier, and they run easiest first, so the book itself is a gentle ramp.
Every board is a released daily puzzle, checked by our solver to have exactly one solution reachable by logic alone. If you feel the urge to guess, you've missed a move — and the Medium Star Battle guide covers exactly the moves this tier asks for.
