Signed, Mr. X

When Everest moves back to a quiet small town with her single mother, she expects awkward hallways and starting over, not a step brother who doesn't know boundaries and secrets that refuse to stay buried. Then there's Alex Ryan, Everests photography teacher. Arrogant. Untouchable. And somehow always in her way. From the start, they clash... but beneath the friction is something neither of them wants to acknowledge.
A month later, Everest begins receiving anonymous letters signed by Mr. X. At first she dismisses them as a cruel prank. But when the messages turn personal and the feeling of being watched becomes impossible to ignore, fear sets in.
Desperate for help, Everest learns that Alex's father is the head detective of the towns police department. When he refuses to believe her, Everest turns to the one person she trusts the least: Alex himself.
Reluctantly teaming up, they begin uncovering clues that suggest Mr. X isn't just watching, he's escalating. And with every answer they find, the danger grows closer.
As suspicion tightens and trust becomes fragile, Everest realizes she can't face this alone. With her friends drawn into the mystery, one question becomes impossible to escape...
How well can you ever really know the people around you, when someone is hiding in plain sight?
