I second the suggestions above, though for some reason my kids did not love the Christian Nature Libery Series …I’d had high hopes for these books, but they did not take hold for us. Maybe they will work for your DD – a lot of detail on bugs and small critters though, so just give thought that this matches for her interests before you purchase. They are great for being a “reader” where there is a lot of material in one book.
Many of the others I suggest below are great for this level of reader, and nice stories, but most are short, maybe 6 chapters per book, so they don’t “last” that long. I’m glad I own them, but I’m glad I have two other young ones that will read next in line because a 6.5 year old does go through them fairly quickly.
Young Cam Jansen series by David Adler (Cam is a girl character) good level and the stories are wholesome.
Sable, by Karen Hesse
Snowshoe Thompson, by Nancy Levinson
The Long Way to a New Land and The Long Way Westward, both by Joan Sandin
Five True Dog Stories, Margaret Davidson
The Golly Sisters, Betsy Byars
I purchased all of these (except the last one) for my second son when he was 6.5-7yrs and he loved all — this level is really where his confidence took off.
I purchased all of these with free worldwide shipping from
http://www.bookdepository.com — ships out of the U.K. so you would receive very promptly!
HTH! Blessings, Andi
