That's good, the book is definitely a worthwhile buy - it has some great photos/illustrations, plus it is a very good read as well. Quite a few photos and childhood memories of the Romanovs also.
Interestingly, it was published in 1979, just before Mountbatten's tragic death so, of course, has no information on the IRA atrocity which is a good thing, in my opinion, because the manner of his death sadly seems to have eclipsed his life somewhat.
You will enjoy it!
