As a disclaimer I haven't read CODE, even though it's been on my list for a while (sounds like I ought to prioritize it!). From my understanding of the style I believe The Gene: An Intimate History by Siddhartha Mukherjee is a similar take on genetics. It stays fairly high level as it doesn't require a molecular biology degree, but Mukherjee gives a fantastic primer on many of the concepts in genetics in a deeply interesting and human fashion. It's always refreshing when non-fiction books manage to weave a narrative throughout in a way that feels natural.
