I really love how the author approaches these complex, multi-layered relationships between her female characters. The connection between Evelyn and Martine is at once that of scientist to specimen, parent to child, sister to sister, self to self. I was enthralled! The ending got a little hand-wavey, but I think it's believable enough that I didn't mind too too much. I also appreciate a book that has a clear message but never has to soap-box to get its point across.
