Since most of the reviews for McKenna and her book discuss the price, I'm going to review the product itself. We got it directly from the American Girl store and paid $105. My daughter saved all year to buy this and we are now the proud owners of two AG dolls. Though I think even the AG price is insane, girls love this franchise. The American Girl marketers are GENIUS.
Anyhoo, McKenna herself is a well-made doll. Her eyes open and close depending on if she's standing or lying down. She is sturdy, with well-stitched clothes and smooth, silky hair that is easily brushed (I never knew this was important when I got my daughter the curly-haired Kanani for Christmas last year, but whoa-boy, get your girl a doll with easy-to-brush hair. Crucial!) The gymnast angle is also a draw for girls of this age.
My daughter is sitting here dictating to me now and telling me that her leggings are a little hard to get on, but the rest of the clothes are nice.
We really like the American Girl stories (even my husband thinks they're good). They're wholesome but with realistic conflicts and resolutions. McKenna is a likable story, too, with the added bonus of a broken leg, rather than some sort of scary villain, being one of McKenna's major problems.
If you're looking for a wholesome, well-made, albeit expensive toy for a girl first to fifth grade, this is a good one.
