At the poetry conference I recently attended, we spent some time discussing patterns of organization for poetry collections. Most people these days think that a collection should have a single unifying theme, but one of the instructors said it can sometimes work to have three or four sections, each with their own tight theme. I'd been trying to get a handle on this collection for the last few days, and it helped when I realized that this book does have a completely different theme for each of the four sections. 
 The first section, and for me the most compelling, are poems about the history of science. There are several poems about Darwin, as well as others about his scientific contemporaries. My favorite poem in this section was "The Last Dodo in Iowa," in which Greger describes walking through the ratty natural science museum in Iowa City until she suddenly comes face-to-face with that remarkable specimen. (When I was there, it felt like I may have been the only visitor in the past hundred years, and Greger captures that feeling very well.) 
 The second section are poems of childhood, and based on the age of the speaker, I have a feeling they are largely autobiographical. The third and fourth sections consist of poems about Florida and England, respectively, which are the author's two home territories at present. 
 As for the poetry itself, Greger is a master of the image, but I wasn't able to connect very much with the emotions behind the images. Perhaps she's just not the right poet for me at this time of my life, but I was glad to have an opportunity to read this collection anyway.
