Alistair MacLean: Y'did Nefesh

In order to marry the love of his life Alistair must convert to Judaism. The rabbis refuse to convert the studious yet impervious Alistair until he finds his Y'did Nefesh (Jewish Soul). As a last resort Alistair under goes "Dassie Goldblatt's Cultural Boot Camp" where neither book learning nor emotional distance are allowed and finds his Y'did Nefesh where he least expected.
