"...Without question, "The Beejum Book" is the crown jewel in her writing career -- it is a literary treasure that delights and enlightens anyone who reads it -- adult or child. At 80, Howell has published a work of enduring excellence, a true classic that is hard to put down once you pick it up.  Only a few pages into the story, you find yourself cheerfully going along for the ride with Teak on the "six-sixty-seven," the magical train full of surprises heading toward Beejumstan..."

...And that the 6:67 came of its own accord independently and directly to Teak in the same way it came to Harry Potter (and Rowling, on a train of course) -- the expected synchronicity.

"If one does not expect the unexpected one will not find it out, since it is not to be searched out, and is difficult to compass."

Heraclitus,  Fragment 18, Clement Strom. II, 17, 4
