I first read this book in the third grade, and have been re-reading it annually for the past 30 years. Nothing in the intervening years has been able to touch it (certainly NOT Harry Potter). It is the spiritual heir to the books of the great English fantasy writer E. Nesbit; it is completely unsentimental, original, witty, and does not talk down to children, something I appreciated even when I was 8. The best part, though, is the clever dovetailing between this book and its sequels "Knights Castle," "Magic By The Lake," and "The Time Garden" -- at one point you'll have the wonderful realization that you're reading the stories of two generations of children from the same family whose "magicks" cleverly overlap! Buy these books, and, if you can, Eager's equally wonderful and final book "Seven-Day Magic" (chickadee tidbits!).
