Quickie comments on some of the books on your list
blyton titles – fun as expected
Wind in the willows - I think I was traumatized by this as a child, but obviously a classic for a reason.
Swallows and Amazons - LOVE THIS SERIES but its not to everyone’s taste. You might want to read the first chapter and see if it bores you (lots and lots of details about camping and sailing, like details about all the different knots they learn) because if it does, reading the entire thing aloud might put you in an early grave.
Half Magic ( eager) - I almost put Time Garden by Eager on my list. These will go quick as read-alouds, but fun.
Belle Prater’s boy (white) - my gut reaction is that this is a little above your kids’ interest level, given their ages. I really liked it, maybe in a few years.
Holes ( sachar) - I liked this very much, some parts might be a little scary.
A wrinkle in Time ( L’engle) – again, I think a little above age level unless your youngest is a sophisticated reader. Magic and stuff, but more philosophy and theory than Harry Potter and co.
Me and my little brain ( fitzgerald) – you don’t really have to read these in order, but this one is toward the end of the Great Brain series.
Great brain does it again – ditto
All of a kind family ( taylor) – very good, especially if your kids like “old-fashioned” stories.
Black Beauty ( Usborne version. very good for a nice condensed one, IMHO) Some of the condensed ones leave out the HIGHLY TRAUMATIZING horse death scene, hopefully this is one of them.
The egypt game ( snyder) Fun, light hearted, fluffy
Linnets and Valerians - oh my gosh, haven’t thought of this in YEARS, I remember loving it
from the mixed up files of basil frankenwiler - I could have sworn I put this on my list, good choice.
I have about 30 or more that are too old ( holocaust stories and WW2 or ww1 time period stories) and my daughter is trying to levitate the dog right now, so I am a little distracted. – I’m dying to know if Twenty and Ten (sometimes published with the title The Secret Cave) is one of your holocaust stories … it’s a good one and age appropriate (and not scary).
How are things going with your dog?
