Description

The first letter arrived on her 18th birthday. It was from the future. And from a boy she had never met — but somehow already missed.

Avni Sharma has always lived a quiet life tucked inside art, silence, and second-guessing. But everything changes the morning she receives a handwritten letter — dated 2040 and signed by someone named Rivan Mehta.

The instructions are simple:

Be at a café. Don’t look for me. And whatever happens, don’t throw away the green diary.

What begins as a strange birthday prank spirals into something much bigger — fractured timelines, forgotten memories, love that exists across lifetimes, and a science project that shouldn’t exist.

As Avni uncovers her connection to Rivan, and the truth about the world she thought she understood, she must face the most heartbreaking question of all:

If time can be rewritten… does that mean love can be undone?

A romantic mystery of letters, memory, and the one person who never stopped believing in her — even when she forgot him.
