About this book

Most puzzle books aimed at this age are either recycled kid books with a darker cover or adult books with the fun sanded off. This one is calibrated for a teenager: the puzzles are hard enough to be worth finishing and the pages do not look like they belong to a seven year old.

Large 8 x 10 inch paperback with one puzzle per page, printed clean on bright white paper with room to work. No cartoon animals, no baby colors. Full answer key in the back.

What's inside

A quick technique page up front covering scanning, pencil marks and hidden singles, then it gets out of the way
Every grid computer-checked for exactly one solution, so a puzzle never dead-ends and never needs a guess
A consistent hard band throughout - no surprise spike in the middle of the book
Room to write in every square, with light pencil-mark space in the corners
Full answers in the back, laid out so checking one puzzle does not spoil the next
