Let me start by saying this book is not for the faint of heart. 'The Girl in the Letter' tackles the dark history of unwed mothers' homes with unflinching honesty. The dual timeline between past atrocities and a modern journalist's investigation creates a compelling narrative structure that keeps you hooked.

What really got me: The visceral descriptions of Ivy's suffering in the home. When she's forced to scrub floors while heavily pregnant, I could practically feel my knees aching along with hers. The author doesn't shy away from depicting the brutal reality these women faced.

The modern storyline provides necessary breathing room between intense historical sections. I found myself racing through chapters to see how the timelines would connect - and wow, that final reveal about the reporter's personal connection was masterfully done.

However, I agree with some reviewers about the asthma plot hole. As someone who grew up with asthma in the 90s (when treatment was better than the 50s), it stretched credibility that an athlete would leave his inhaler so far away during games.

The twin identity confusion also bothered me. After establishing their vastly different living conditions, it's hard to believe they'd look identical years later. This felt like a rare misstep in an otherwise meticulously researched book.

Content warning: There are graphic depictions of abuse that left me needing to take breaks. The scene where nuns withhold medical care still haunts me weeks after finishing.

Despite these flaws, I couldn't put it down. The writing shines when exploring how institutional cruelty persists when good people stay silent. That message resonates painfully well in today's world.

Final verdict? 4/5 stars - a powerful if imperfect historical thriller that educates as much as it entertains. Just keep tissues handy and maybe don't read before bed.
