I'm definitely the target audience for this book. My knowledge in geology and paleontology is limited to a foggy memory of the basics, if that.
I could already tell after reading Chapter One I was going to enjoy Your Inner Fish. Like some people have already pointed out, Neil Shubin writes succinctly and passionately about a subject I think some people find intimidating or dull. I needed a book like this when I was younger.
I read a review of the book online and one of the things the review emphasized on was the fact Neil Shubin refused to get into it with creationists in his book. I'm not sure why it matters. Even starting from the first page, he already addresses a question many creationists have about the fossil record and why there are "gaps" in it. I think he did a brilliant job explaining the conditions needed for fossilization, why fossils are rare, how they plan their expeditions to find fossils and how some of the time it's luck that steers them in the right direction. Everything is so simple. I will suggest this chapter (and probably the entire book) to any creationist I talk to in the future.
I chuckled near the end of the chapter when the pre-schoolers were trying to determine what Tiktaalik was. It makes me wonder why the message isn't so straightforward for my parents or anyone I know offline.
