My little girls (10 and 8) like the “Royal Diaries” series. These generally have excellent historical research and good values.
My son would feign to be put off by the “princess” aspect. Truth be told he will devour anything with a historical angle. I frequently catch him dipping into my daughter’s “American Girl” books, at which poit he looks up and goes “WHAAAATT!”.
“Nothin’, dude. Reading is cool.”
Thanks for that recommendation. My oldest just turned 10 a couple of weeks ago and is devouring books this summer (not good for the digestion, I know). She loves history (like her dear mother) and those would be right up her alley. I see our local library has several of that series.
