This one almost seems like a "Published by the Author's Estate". In a hastily re-written 80's plot, the family returns to a world gone wrong. Father Keith Stoner begins his own plan to set things aright tying in to The Grand Tour; meanwhile the children begin their own quite immature attempts at solving problems. Things start coming to a head, it should be time for the next arc where they have might have created a world afraid of beings of immense power, right? No, the end!

This book is best described as an extensive cheatsheet to Persian. It is intended to accompany other books, and is thus light on vocabulary, drills, and self-tests. However I've found it to be a fantastic guide, and constantly refer to it. It is structured to follow along as you are learning; it starts out with the alphabet showing the alternative forms of many letters, then a brief section nastaliq and shekasteh, before moving on to plurals, ownership, then verbs, ezafeh, and other more advanced topics. Definitely one to have, in general anyone who has used or looked through my copy has been impressed, even native speakers.
