Five years ago, the mysterious masked musician known as Il Cigno vanished. Her disappearance has haunted him ever since.

Matteo Rossi has two equally challenging roles: mercenary assassin and guardian to his boisterous thirteen-year-old niece, Alessandra. He knows how to track a target, take down a threat, and disappear without a trace. What he doesn't know how to handle is a teenager who has started breaking the rules—or the feisty music teacher who is encouraging her to do so.

When Mia Mills built her new life as a music teacher in the Italian lakeside town of Lacustria, she had one rule: keep her head down and stay out of trouble. But Mia has never been the type to walk away from someone who needs her help. When her talented student Alessandra secretly applies for a prestigious music summer camp, Mia is determined to help her chase her dreams—even if it means going head-to-head with her overprotective guardian.

Mia knows getting close to people only puts them in danger. But as she is drawn deeper into the Rossi household, she finds herself wrapped in the warmth of a family she never expected to become part of. With each day she spends there, she indulges in the most dangerous ideal of all: hope for the future.

As Matteo and Mia try to resist the magnetic pull between them, the truths they are both hiding threaten to destroy everything they've built.

Because some truths can set you free.
And some can get you killed.
