I can partly recommend "OSI Explained: End-to-end computer
communications standards" by John Henshall and Sandy Shaw.  I can only
partly recommend it because I've only read part of it!  What I have read
is good and it has had good reviews.  It is written by two colleagues
whose offices are about 30 feet from here so I must express a kind of
interest, though not financial.  The authors are working on a second
edition.

"OSI Explained" is published in the UK by Ellis Horwood and distributed
(presumably outside the UK - I know it's available in N.America) by
Halsted Press, a division of John Wiley and Sons (it says here).

ISBN of Ellis Horwood edition: 0-7458-0253-2
     of Halsted Press edition: 0-470-21100-8

Following is a quotation from A.A.Milne's 'The House at Pooh Corner'
included in Preface:

     Owl explained about the Necessary Dorsal Muscles.  He had explained
     this to Pooh and Christopher Robin once before, and had been
     waiting ever since for a chance to do it again, because it is a
     thing which you can easily explain twice before anyone knows what
     you are talking about.
