About this book
The publisher's full description is above, next to the cover. This title is part of our adults-and-teens shelf — the same big-question format, written for readers who outgrew the kids' section but never stopped asking why.
Why grown-up question books work
The question-per-entry format that works for kids works for adults for the same reason: short, self-contained answers you can read in minutes and actually remember. Good bedside books, good commute books, good gifts.
Who it's best for
Teen and adult readers — see the title above for the intended audience. Not part of our children's collection.
The gift that gets read
For the person who already has everything except the answers — free shipping and the 30-Night Guarantee included.
