I kind of love Crazy Ex-Girlfriend. I'm actually rewatching it currently because the music makes me laugh. I can't remember where I saw that Rachel Bloom had a memoir out, but it was a must-read once I heard about it. I Want to Be Where the Normal People Are has the typical Bloom vibe from the show.
It's hard to outline the plot of the book. Bloom shares stories from her childhood through the beginnings of her acting career, up until the beginnings of Crazy Ex-Girlfriend. It's a memoir in the sense that it is her stories, but not a memoir in a full autobiographical sense.
While somewhat chronological, each chapter essentially stands along, full of Bloom's witty observations and self-deprecating humor. It's closer to Ellie Kemper's My Squirrel Days or Trevor Noah's Born a Crime, humorous stories, but not a full biography.
That said, if you like Rachel Bloom's comedy or her shows? You'll like the book. It's very similar to the sense of humor she shows in Crazy Ex-Girlfriend, and you can see where her ideas for the show come from. I'm glad I read it, but kind of wondering if listening to it (assuming she reads the audio) would have been even better.
