I am Spock by Leonard Nimoy

O.K. so once you get past the first 150 pages (roughly the length of the first book) the great chunks of text transposed from the first book thin out.  So my recommendation is if you buy both books don’t bother starting the second one until about half way through.  “I am Spock” was alright, it added a few snippets not in “I am not Spock” but didn’t add much more insight into Nimoy himself.  If you want Nimoy’s Autobiography then buy either book, but don’t bother buying both.
