Long before Sierra Hart knew his name, Mason Wilder had already made her brother a promise.

Born into one of Geneva’s most powerful watchmaking families, Mason spent years resisting the future everyone else had chosen for him. He wanted his own work, his own decisions and enough distance from the Wilder name to discover who he might become without it.

Then he met Aaron Hart.

Their friendship drew Mason into a private world of experimental medicine, artificial intelligence and research valuable enough to attract the wrong kind of attention. Aaron believed technology could reach people medicine had already given up on, while Mason understood how quickly a discovery capable of saving lives could become dangerous once money and power entered the room.

When Aaron’s life is destroyed by an accident Mason never fully believes was accidental, one final promise leaves him responsible for someone he has never met properly: Aaron’s younger sister.

Sierra is supposed to remain a name Mason watches from a safe distance. Instead, curiosity becomes fascination long before he admits it, and protecting her quietly becomes harder every time their lives move closer together.

Before I Found You is Mason Wilder’s story before Winter’s Touch, revealing his family, his friendship with Aaron, his connection to the hidden world surrounding Calix, and the promise that eventually leads him to the woman who will change everything.

He promised Aaron he would keep Sierra safe.
Nobody warned him what would happen when he finally fell for her.
