Clockwork Hearts

In a world of steam-powered cities, mechanical wonders, and ruthless imperial control, brilliant inventor Evelyn Ashbourne survives by staying hidden.

Deep beneath the industrial kingdom ruled by the Crown, Evelyn secretly builds impossible machines within her enchanted observatory-an underground sanctuary concealed from the Crown's hunters and dimensional authorities. Her greatest creation is the Rift Engine, an experimental device capable of tearing open pathways between worlds.

Then one disastrous activation changes everything.

Katsuki Bakugo-a fiery, sharp-tongued fighter from another universe-is violently pulled into Evelyn's steampunk world after the Rift Engine destabilizes. Stranded in a reality without quirks, hunted by the Crown, and trapped in the identity of a dead alternate version of himself, Katsuki is forced to rely on the guarded inventor who accidentally brought him there.

But the more time they spend together rebuilding the damaged Rift Engine, the more dangerous their connection becomes.

As Crown Inspector Vale closes in and whispers spread about forbidden dimensional technology, Evelyn and Katsuki uncover a terrifying truth:

The Rift Engine is no longer simply a machine.

It has bonded itself to them.

Now hunted across steam-covered cities, hidden underground sanctuaries, moving observatories, and war-torn skies, the two must survive impossible odds while navigating a slow-burning romance neither of them expected.

But opening the door between worlds may have awakened something far greater than either of them imagined.

And if the Rift Engine fully destabilizes-

it won't just destroy one world.

It could destroy them all.
