Four rival heirs. One impossible bond. A girl the academy spent years pretending didn't matter.
Isla Thorne has spent her whole life being underestimated at Ashgrave War Academy, the last defense between the Houses and the Veil, a centuries-old magical incursion no one fully understands. Then her "weak" magic tears loose mid-exam, and she learns it was never weak at all. It was suppressed, deliberately, because it's exactly the kind of power a five-point Sworn Bond requires.
Kael, Varen, Dorian, and Soren are four warriors from four rival Houses who can't stand each other. They're also the only four compatible enough to bond with Isla. As the Trials force all five of them into proximity none of them chose, something unprecedented begins forming, four bond-marks, one girl, and a connection that has never once succeeded across Houses in the academy's recorded history. Someone at Ashgrave has spent years making sure it never would.
She was never the weak one. She was the one they were afraid would wake up.
