You might consider Neil Shubin's *Your Inner Fish*. It is very well written and discusses his team's discovery of *Tiktaalik* to teach about the discovery process and scientific method. The book will also appeal to students with a wide range of interests because Shubin draws on multiple lines of evidence, including genetics, embryology, anatomy, and paleontology, to tell his story. My introductory biology students at Athens Technical College are encourage, but not required, to read it. Most of my students enjoy it.
