Infernal Frequencies (The Fallen Response Unit Book 2)

by S.D. Maynard

About this book

Los Angeles is a city of hidden signals, and Luna Cross is the only one tuned into the frequency of the apocalypse. Gifted with synesthesia and a ruthless technical competence, she hears the static that whispers secrets—and tonight, that static is screaming a warning. When a weaponized sound starts turning the city into a slaughterhouse, Luna is forced to team up with an ancient, lethal guardian who has spent decades running from his own shadow.

Raziel is a fallen angel haunted by a history he cannot outrun and a faith he no longer possesses. Standing six-foot-three with piercing violet eyes, he is a man—or something more—who has vowed never to let another human close enough to be destroyed by his presence. Yet, Luna crashes through his defenses like a live wire, igniting a dangerous, high-voltage chemistry that threatens to consume them both.

This gripping urban fantasy delivers a masterclass in tension, blending supernatural stakes with a slow-burn romance that will keep you awake until 3 AM. As they fight to find harmony in the chaos, they must decide if their connection is a salvation or a death sentence. For fans of gritty paranormal romance, this is the addictive, high-stakes journey you have been waiting for.

The magic system is built entirely on real sound engineering — frequencies, harmonic resonance, subsonic weapons hiding in subwoofer cabinets — and it works because it feels grounded. Then there's Raziel....

Really good book!

However, I felt like skipping parts a lot because it was TOO technical when it didn't need to be so detailed. With that said, it did not ruin the book for me. I thoroughly enjoyed it! )

Waiting impatiently for the next book.

⭐⭐⭐⭐⭐ If J.R. Ward wrote a Fallen angel who hadn't been touched in 83 years I need everyone to understand what S.D. Maynard did to me with Raziel. Six-foot-three. Violet eyes. A jawline a Renaissance sculptor would weep over. Eighty-three years of self-imposed exile, sleeping above a dead studio, drinking bad mezcal, and refusing to let anyone close. Then a five-foot-one sound engineer with combat boots grabs the front of his jacket and his entire body comes back online after eight decades of...
