One Scar. One Entity. One month to save the world — or be erased from it.

After the Entity stirred and Mira's body shattered under the weight of its power, everything changed. The Rivermouth Scar isn't just a wound in reality — it's a prison. And the being trapped inside isn't content to stay silent anymore.

With the Gatekeepers issuing a grim ultimatum — seal the Scar or be "excised" with it — and Chimera accelerating their plan to use Mira as the catalyst for dimensional convergence, time has officially run out. The Entity is stirring. The Blight is spreading. And Mira is running on fumes.

Every path leads to ruin.

But Mira refuses to give in.

Haunted by reality flickers, hunted by a cosmic death cult, and forced to betray the people she loves to protect them, Mira's choices narrow by the day. Her attempt to stabilize the Threshold failed, and even her passive probe of the Scar nearly destroyed her. Now she must do the unthinkable: connect directly with the Entity. Understand it. Reason with it. Or, if necessary... contain it again.

As friends fracture under pressure, conspiracies rip through what remains of order in Oakhaven, and power beyond imagining surges inside her, Mira is forced to reckon with who she is — and what she's becoming. No longer just a girl with a gift. No longer just an Anchor.

She's the epicenter.

The Final Crossing is a pulse-pounding crescendo of magic, mystery, betrayal, and identity crisis — the fifth installment in The Boundary Walkers saga. Prepare for emotional wreckage, mind-breaking revelations, and a finale that redefines what it means to protect a world that never wanted you in the first place.
