Quantum Heartstrings: A cozy spy mystery brimming with secrets, sparks, and a dangerous masquerade
Secrets always come with a cost.
This time, the price might be Anna’s heart.
After surviving espionage, sabotage, and one too many undercover disasters, Anna Walker is finally settling into life at Quantum. The bad guys have been caught, the city is safe… and yet something feels unfinished.
When a glamorous masquerade at a private conservatory draws Quantum back into the spotlight, Anna finds herself pulled into one last high-stakes mission—one layered with hidden agendas, dangerous technology, and feelings she can no longer ignore.
As encrypted clues surface and a shadowy mastermind prepares a public “demonstration,” Anna must rely on her instincts more than ever. Undercover assignments blur personal boundaries, old routines begin to crack, and sparks fly in places she never expected. With lives on the line and her heart caught between clarity and fear, Anna faces a choice she can’t postpone any longer.
Because this time, it’s not just the mission at risk.
It’s everything she’s built—and everyone she’s come to love.
Quantum Heartstrings is the finale of the Quantum Cozy Spy Mysteries, a lighthearted yet thrilling conclusion brimming with secrets, sparks, and a dangerous masquerade. Perfect for readers who love cozy mysteries with clever heroines, undercover antics, slow-burn romance, and satisfying happily-ever-afters.
