Read first, or watch first?
If your child came to Anne through the Netflix series, say one thing before they start: the book is sunnier, and the show's darker inventions aren't in it. A kid who wanted more of that edge may stall; a kid who loved Anne herself will find the concentrated version. The 1985 miniseries and the book agree with each other, so that pairing works in either order. And it reads aloud beautifully, if you can do the voices.
