One question I've been seeing a lot on American Girl's social media lately is "When will the wishbook come out?" If you know what it is, great! If not, a wishbook is one of those huge holiday catalogs that you get every year.
Like, this one from 2016,
I don't have an official answer, but I personally think that it will be out by the beginning of November- because that's when Halloween is over with and people gear up for Christmas more. They've come out in October in the past, but I wouldn't count on it releasing in October this year because the release was later than normal.
