She doesn't take prisoners. She takes souls.

The Silent Binds is the eighth book in the epic Metalwood Saga series.

As the cataclysmic Fall hurtles closer, threatening to obliterate the fragile worlds of Valaralda and beyond, Trey finds himself bound to an ancient, magical key known as Edrafen. Said to be the only hope of activating the Defense Mechanism and averting total annihilation, Edrafen begins to intertwine with Trey's very soul, its enigmatic power both guiding and consuming him.

But Trey's quest is imperiled by Cariel, a Prime Mage of terrifying power who uses her soulbinding magic to enslave Arra and Rylan. Driven by obsession and cruelty, Cariel amasses a legion of unwilling servants, forcing Trey into a dangerous game of strategy and sacrifice.

The battle comes to a head at the fabled Palace of Memory, where ancient truths, haunting betrayals, and the fate of the universe converge. To stop Cariel's reign of terror and unlock the true purpose of Edrafen, Trey must confront the ghosts of the past and make an unthinkable choice—one that could save countless lives or doom them all.
