The one huge difference to the one in the book is the length.  Mine was the exact same length as the one pictured, until blocked.  I didn't stretch it.  As a matter of fact, I tried to scrunch it up a bit as it was drying.  I am on the taller side,  5' 8".  (Well, alright 5' 7 3/4", but who counts that quarter of an inch I was shorted) ?   And, it comes to my knees.  Alright for me, but if you wanted it shorter, you could easily modify the pattern.
Pattern:  Ruby, Debbie Bliss cashmerino collection.

Yarn: 19 balls, Debbie Bliss cashmerino aran in green 024

Needles: size 8 (yay for 8's)

Modifications:  I did slim down the sleeves quite a bit.  I cast on 66 stitches, instead of 80.  I did increase to the amount required, by increasing the number of times increased.  (Make sense)?

So, the pattern has you increasing every 7 or 8 rows.  After doing one set of the 24 row repeat, I started to increase on rows 3,7,11,15,19 and 23.  

Notes:  This sweater is knit from right to left, instead of from bottom to top or top to bottom. If you wanted to make it shorter you could take off one or two of the cables.  

I absolutely LOVE this sweater.  I really can't say enough about it.  It is one of those sweaters that will be worn a TON in my life.  I do love my sweater coats, and this one seemed to have joined the others very nicely.
