Alone

Alone is a gripping psychological thriller and mystery novel by bestselling author Lisa Gardner, and the first book featuring Massachusetts State Police Sergeant Bobby Dodge. When Bobby makes a split-second decision to shoot a man he believes is threatening his wife, the aftermath sets off a chain of events far more dangerous than a single night of domestic violence. As investigators and media descend, Bobby finds himself trapped in a web of secrets, lies, and a very powerful family with something devastating to hide.

At the center of the story is Catherine Gagnon, a survivor whose haunted past is impossible to separate from her dangerous present. As Bobby grows closer to the truth about what really happened inside that house, he begins to question everything he thought he knew about the victim, the shooter, and himself. Lisa Gardner masterfully layers tension upon tension, refusing to let readers settle into easy assumptions about guilt, innocence, or justice.

Gardner's greatest strength is her ability to create characters who feel rawly human, flawed, and utterly believable under pressure. Bobby Dodge is a hero built not from invincibility but from conscience, and Catherine is one of the most psychologically complex survivors in contemporary thriller fiction. The emotional depth that runs beneath the breathless pacing is what elevates Alone far above standard genre fare.

For fans of psychological suspense, police procedurals, and thrillers that explore trauma and resilience, Alone is both an electrifying read and a deeply felt character study. Lisa Gardner delivers the kind of story that keeps you reading through the night, second-guessing every chapter until the very last, unforgettable reveal.
