This was a beautiful, subtle, quiet book. When Lo finds an ad marketing a free car (she's a freegan), she doesn't realize that it actually comes with a catch: Blanche, the car's seller, is at the end of her life and she wants Lo to find her son. Lo eventually agrees with the help of local car mechanic John, who finds Lo all too interesting. Lo is staunchly anti-capitalist, and it appears, to many readers' dismay, ableist and at times a little racist. Whether this is or isn't the intent of the author or the author's own perspective sneaking in isn't so much the point as is Lo's growth. Lo, over the course of her road trip, must reckon with the fact that most people don't fully agree with her perspective, though they can find something to like about it. However, Lo is firmly against any opinion that seems to differ from her own. She closes herself off, from potential lovers, family, and friends. It's only until she returns to her small town, having failed at her mission, that she realizes what this has meant for her.
This book is not about changing. Not quite. This book is about realizing that something needs to change.
Manmade Constellations also oscillates between Lo and Jason, Blanche's son. When Jason realizes that his girlfriend is pregnant and she asks him to leave, he does, not realizing that the other choice is to stay. Jason, like Lo, has his convictions, but he seems to be as easygoing as Lo is rigid. The two, though not simultaneously, must deal with their mothers: Jason must come to terms that Blanche really did do her best, even if her best wasn't good enough, and Lo must come to terms with the fact that her mother never really wanted her, even after all these years. Where does this leave a person? Can they reckon with these facts of their histories?
Structurally, Lazzara makes an interesting choice. About every 25% of the book, she inserts facts about fireflies. She also allows for short chapters so that characters may tell their stories in their own words.
Overall, this book is endearing. It's not a book that ties everything up neatly, and there's as much failure for the characters as there is room for growth--which is to say, a lot.
