half-magic-sequels

When looking up Half Magic yesterday, I learned that the author, Edward Eager, wrote several other books. Which sounds most interesting?

• Knight's Castle: Cousins, children of two of the girls in Half Magic, find magic in a toy castle, paying homage to many tales from the children's novels of E. Nesbit3
• Magic by the Lake: sequel to Half Magic, following the same four children in their adventures on summer vacation2
• The Time Garden: direct sequel to Knight's Castle, featuring time travel through the herb thyme1
• Magic or Not?: Adventures of another set of children, but they are ambiguous, leaving the reader to wonder if the imaginations of the children have just run wild this time1
• The Well-Wishers: sequel to Magic Or Not?, telling a deeper, more serious story
• Seven-Day Magic: Yet another set of children check out a library book and find it carefully records their words, leading to new magical adventures1
