This memoir/biography is done in an interesting format: there are reflections from the author as well as pieces from the journal the author's grandma started before committing suicide. Raab does an excellent job interweaving her grandma's story with her own.
Regina's story is fascinating. She could've excelled at so many things, but the world wars tore apart her family and derailed her plans. Regina planned to be a doctor and was well on her way to meeting that goal despite being essentially orphaned. Her reflections reveal her to be a very determined young woman who didn't let the hardships she faced get her down. So what circumstances caused her to take her own life after all those years of survival? While Regina's Closet doesn't provide that answer, it does give many insights into Regina's life.
