Shattered Verse (Mortals & Muses #2) by Layla Nox:
 
Jay’s rockstar dreams are on life support until he meets Lyra, the new neighbor who seems to understand the melodies in his head better than he does. What starts as quiet porch-side chats becomes the catalyst for his return to music, pulling him back from the brink of giving up. But as their connection deepens, Jay discovers that Lyra’s presence is no coincidence, and her true nature is tied to a secret that spans from the modern world to the realm of ancient myth.

To claim the future he’s always wanted and the woman who saved his soul, Jay must confront primeval forces that view human talent as a plaything. With the help of some familiar faces who have braved these divine shadows before, he’ll have to risk a journey into the dark heart of the underworld to bargain for a freedom that was never meant to be theirs. In a world of celestial interference, Jay is about to learn that the most powerful song is the one you’re fated to sing.
