All worlds are dying, and it’s up to one broken and dysfunctional family from Earth—the Wellsleys—to save the day.

Cancer-ridden Ella celebrates her fifteenth birthday beneath an enchanted mountain, but it is what lies even farther below—the mysterious Star in the sea—that demands she grow up quickly. While Ella grapples with the sacrifice she must make and the lies she is forced to tell, her mother, Tessa, is hell-bent on protecting her.

Through bizarre encounters, love-sick Tessa realizes that she is not the lonely orphan she believes. Her husband, Arden, and father-in-law, Archie, are not the only ones with magical bloodlines. This revelation changes everything.

As Archie chooses to embody his unexpected ancestry, he learns that leading the charge in the ultimate battle against evil won’t be as easy as he thought. He’ll need his family—and the strange allies he has gained—by his side to give Ella enough time to set things right.

Can they defeat the unstoppable Millia sands—and another unexpected foe—before everything they hold dear is destroyed? Or will their adventure tear them apart for good? The finale to The 8th Island Trilogy will hold you spellbound until the final page, and long after.
