Until Kingdom Come

Max Fallow has never been a natural multitasker-but when the people he loves are in danger, he will burn himself to the ground to protect them.

His younger brother Seb has just been diagnosed with a structural congenital heart condition that worsens under stress. At sixteen, Seb is volatile, exhausted, and terrified in ways he refuses to admit. He pushes back against everything that might help him: school, medication, meals, even conversation. The only thing he seems to want anymore is sleep. Surgery has been offered, but Seb can't decide whether he wants to fight for his future... or run from it.

Max wants to be the brother Seb needs. But King Andre is still missing-and since the day Andre sent his final letter, no one has been able to find him or confirm he's alive. Everyone knows he was due for surgery on his damaged leg weeks ago. Everyone knows he should have been recovering by now. And everyone knows Max is the one person who might be able to reach him.

Max needs rest. He deserves a moment to breathe after finally stopping Nikolas and ending the thefts from the Calypso and the Chariot. But caring for others has always been easier for him than caring for himself. Despite the worsening instability in his neck, he pushes forward-comforting Seb, trying to pull him back into the world, and quietly tracing every lead that might bring him to Andre.

Max will carry everyone he loves, no matter the cost. But as the weight grows heavier, one question rises with it:

How long can Max hold the world together before he collapses-and who will he take with him when he falls?

"Every vow outlives the man who swore it."
