(Full disclosure: this book was written by my mom, though I do not intend for that to influence my review.)
This book tells stories from the life of Saint Clare, as well as some of the early Clare sisters, from the point of view of those who knew her. The book is sort of pious historical fiction. Most events and people in the book are recorded somewhere, but many details are filled in, including aspects of the lives of early sisters that we know nothing about, or details about how Clare did certain things or learned about certain events, etc. The author does a good job in the appendix of separating accepted facts, from things that scholars disagree on, from what is completely fiction.
The book is a fairly easy read, and does seem to record all of the major events in Clare's life. The stories are written to be interesting, and to explore individuals' personal emotional and spiritual struggles (though I'm sure some of it would sound very strange to those unfamiliar with the Catholic spiritual tradition, especially since the emphasis on fasting and penance was much greater in Clare's time than it is now).
My main complaint about the book would be that the style is not really my favorite. I think I prefer facts, personalities, and events to be described outside of a story context (when it comes to telling history), as I think then it is easier for me to see the big picture. Since each chapter is from the point of view of a different person, I also had a hard time keeping track of the personalities and biographies of all the different people involved (especially the different sisters) (though this may be because I read the book over the course of months). I also find myself questioning some of the fictional details (would Clare really have said that, or would St Francis or one of the other sisters really have acted that way?)
Overall, I enjoyed the book and learning about Clare. I think it is appropriate for someone who wants to learn a bit about Clare but enjoys stories more than traditional biographies.
