What if grief had the quantum power to shatter reality?

For fans of Sea of Tranquility, Dark Matter, and The Midnight Library.

Following the sudden, shock loss of their partner, a nameless narrator finds the fabric of the everyday world beginning to fray. Strange anomalies slip through the cracks of existence, suggesting their intense sorrow has unlocked something impossible: a doorway into the multiverse.

But they are not the only ones navigating these fractured timelines. Others are moving through the quiet spaces between worlds—some driven by their own desperate losses, others guarding the boundaries of reality with dangerous intent.

As the universe splinters, the infinite expanse offers a temptation: How far would you cross the boundaries of space and time to hold the one you love just one more time?

The Tumbler is a lyrical, mind-bending exploration of the physics of sorrow, the permanence of change, and the lengths we go to outrun our longing.
