Echo Switch

What if you could step into someone else's life for ten minutes... and never fully come back?

In a decaying warehouse on the outskirts of Holly Pond, Alabama, brilliant but broken neuroscientist Elias Crowe has created Echo Switch - a rice-grain neural implant that lets users temporarily swap consciousness with another person. Marketed as "empathy training" for the rich and desperate, it promises the ultimate escape: feel the ocean on borrowed skin, live a stranger's perfect day, become anyone you want.

When Mia Reyes's best friend Harper returns from her first "empathy vacation" humming songs she's never heard and craving things she's never wanted, Mia knows something is terribly wrong. Harper is changing - slowly, insidiously - as fragments of other lives bleed into her mind.

As Mia digs deeper, she discovers the terrifying truth: the swaps leave echoes. Residual memories, habits, and desires that don't fade. They layer. They spread. And they're spreading fast.

Now Mia must team up with the very man who built the monster to stop a growing network of fractured minds before the echoes consume them all - including the one person Elias can't let go.

Gripping, atmospheric, and disturbingly plausible, Echo Switch is a psychological sci-fi thriller about identity, grief, and the terrifying cost of borrowing someone else's life.

Because some things you can never return.
