Caller Unknown by Gillian McAllister | Psychological Thriller PDF

Caller Unknown by bestselling thriller author Gillian McAllister is a gripping psychological suspense novel about every parent’s worst nightmare: a missing child and a terrifying anonymous call demanding impossible choices.

When Simone arrives in Texas to reunite with her daughter Lucy after weeks apart, what should have been a joyful mother-daughter vacation quickly turns into horror. Lucy vanishes overnight, leaving behind only strange clues, a mysterious burner phone, and chilling messages from an unknown caller claiming to have kidnapped her.

As the threats escalate and time runs out, Simone is forced into dangerous decisions that test her instincts, morality, and trust in everyone around her — including the police, her husband, and even herself.

Packed with emotional tension, twists, and relentless suspense, Caller Unknown explores motherhood, fear, survival, and how far someone will go to save the person they love most.
