Steel Echo
A Novel by Astra K.

Some echoes never fade.... No matter how fast you drive

Zara Voss swore she’d never race again. Not after the night that left her broken, memory fractured, and a world she once ruled turning its back on her. But when a cryptic message lures her back to the underground circuit, she realizes the past isn’t done with her yet.

Two men stand in her way.

Riven “Rev” Calloway—silent, unreadable, and the only racer who ever matched her on the streets. He’s been keeping his distance, but his eyes tell a different story—one filled with secrets too dangerous to uncover.

Cassian “Cass” Laurent—the golden boy turned investigator, the one who picked up her shattered pieces and made her believe she could move on. But beneath his perfect facade lies a truth he’s desperate to keep hidden.

As Zara dives deeper into the shadows of the racing underworld, the echoes of that fateful night grow louder. The streets whisper of betrayal, of rivalries that never died, and of a truth she might not survive knowing.

Because someone doesn’t want her to remember.

And if she does—this time, they’ll make sure she never comes back.
