All her fault
Marissa Irvine's worst fear becomes a chilling reality when she arrives to pick up her son, Milo, from a playdate. The woman who answers the door at 14 Tudor Grove isn't a familiar face, nor is she the nanny. And Milo? He's gone.
The quiet Dublin suburb erupts in panic. As the search for Milo intensifies, an unexpected suspect is named, igniting a firestorm of speculation. Four women are intrinsically linked to the disappearance. While only one may have taken the boy, suspicion casts a long shadow over them all.
In a community fractured by secrets and unspoken truths, the line between victim and villain blurs. Who holds the key to Milo's fate, and who is truly to blame?

Andrea Mara sets a chilling scene from the very first page of All Her Fault, plunging straight into a chaotic and terrifying disappearance. The narrative operates on a deliberate timeline, with a slow burn in part one that gradually picks up to a steady medium pace through parts two and three. Even with the slower start, the short chapters keep the momentum moving. I liked how the story jumps between several points of view, keeping the focus mostly in the present day with just a few well-placed, brief flashbacks to provide context.
There is a vast cast of characters to keep track of, and while no single perspective steals the spotlight, the shifting viewpoints create a surplus of suspects. Almost everyone acts suspiciously at some point, and the author uses this to scatter a variety of red herrings throughout the plot. Rather than feeling cheap or misleading, every single false lead gets a logical, satisfying explanation by the time the truth comes out. The core twist caught me off guard and shifted the entire perspective of the crime in a clever way.
The conclusion is brief but highly effective, avoiding massive information dumps while tying up the necessary loose ends. It provides the right amount of closure without dragging out the aftermath. If you like multiple points of view, suburban paranoia, and vanishing child mysteries, then you will enjoy this book.
