this is pretty phenomenal. i find it mostly phenomenal as a piece of self-writing, though it's also written beautifully.
i admire trauma memoirs that embrace the necessary fragmentation of trauma. once you make a memoir of trauma linear, coherent, and cogent, it seems to me you lose something. trauma never presents itself in coherent narratives and it may be okay to superimpose coherence to a traumatic experience but imo something will get lost. so i really like the back and forth that sundberg does in this book, and admire how she does it. cuz the other thing is, fragmented thoughts don't look good on page unless you work your heart out to make them look good and readable. there's this fine line between the raw fragments of your traumatized mind and the coherent narrative you would like to present because it has to be readable. if you have ever spent time talking to a severely traumatized person trying to talk about their trauma, you know it's very hard to follow. so a book that honors the fragmentation but also makes it possible for the reader to follow is a book that hits that fine line and treads it all the way through.
i don't think you can do this unless you have gotten a pretty good hold on your trauma, either through therapy or through talking it over with others or through serious self-work. sundberg did the therapy round quite a bit (couple, individual, the works), and i admire tremendously how she processed and owned her trauma enough to make it legible to us. this is backbreaking, soul-crushing work, so kudos to her for the determination to see it through.
what is most startling in this memoir, in my opinion, is how seriously and determinedly sundberg questions herself. she goes back to her past, and, thank god, legitimizes her trauma in the description of sexual abuse she received as a child, but never places any serious burden on her parents, or at least she describes them as distant but also present and eager to help. this is generous, but it's hard not to read in the narrative some degree of childhood abandonment.
and then sundberg goes on and places quite a bit of blame on herself for triggering her husband's violence and thus causing the failure of her marriage.
she tries to find a way to locate where his violence comes from in his life, but she can't, so this remains a mystery for us too. but she takes quite a bit of responsibility for it all, and while that too seems generous (and maybe it is, i dunno, i can't judge), it is also heartbreaking.
