Knowing this story is based on true events makes it a tough pill to swallow. Kids are so innocent, born with curiosity, trust, dependent on adults to love them, teach them, and protect them. Monsters are very real in this world and pret on the innocent. This book is well written. Unfortunately I find Agent Adams to be dry, stuffy, and extremely reclusive. Her character gives me anxiety. I hope that changes in the next two books. I will certainly read this trilogy all the way through.

The First Thread is an utterly gripping, emotionally devastating psychological thriller that left me breathless and haunted long after I turned the final page. Nadija Mujagic masterfully captures the panic, helplessness, and heartbreak of a parent’s worst nightmare - and wraps it in a tense, beautifully layered story that is impossible to put down.
Mujagic doesn’t just tell a story - she immerses you in it. The writing is razor-sharp, the atmosphere thick with dread, and every twist lands with a punch.
What really sets The First Thread apart is that it’s based on true events. That connection to real life adds a whole new level of depth and makes the story even more chilling. Mujagic sheds light on a dark chapter in American history and gives a voice to families who never got answers.
If you’re a fan of psychological thrillers that are as heart-wrenching as they are suspenseful, this book is a must-read.
