"Travels with Trilobites" is a very informative, accessible text that both experts and amateurs are bound to enjoy. 

Secher strikes the perfect tone - not too academic but not too conversational - in order to share his love and knowledge of trilobites with experts and novices alike. If you're new to the topic, or only have a trifling of knowledge (like myself), this book is bound to be an exciting read that may very well kickstart a new fascination with prehistoric fauna. In fact, by the time I reached the Silurian period, I was completely hooked and had already started searching "how to find trilobites near me". 

The accompanying photographs are absolutely stunning, and I could honestly spend hours revisiting them alone. 

My only criticism is the lack of diagrams. It would have been nice to see a general anatomy diagram or perhaps a diagram of one or two select species from each time period.
As a novice, I found myself really wanting to know what parts of the trilobite I was looking at and ended up searching for diagrams online to refer to as I read. 

Overall, I found this to be an enjoyable, easy to understand, but highly informative book.
