The Arm of the Starfish by Madeleine L'Engle is the story of a young man named Adam Eddington who has landed a summer job abroad with a renowned marine biologist, Dr. Calvin O'Keefe. Due to unforeseen circumstances he winds up caught in the middle of an international conspiracy between Dr. O'Keefe and those that would steal his work. Adam must figure out who he can trust and decide whose side he wants to be on, but this decision is not as simple as he would like.
This book was an ok read. It was mostly a mystery thriller type novel with some light science fiction mixed in. The scientific concepts presented in the book were very interesting and there was a good bit of action as well. I'm not sure I entirely liked where the book ended though and felt it could have done with one more chapter to provide some additional closure, but I suppose the author wanted to leave that up to the reader's imagination. This book crosses over with L'Engle's Time Quintet series and features characters from that series, but all grown up with children of their own. This book takes place between books four and five of the Time Quintet and while it's not necessary to read the first four books before reading this book, I would recommend reading this book before reading the fifth book of the Time Quintet.
