Robyn Hood has faced monsters, tyrants, and the darkness within—but nothing like Judgment Day at S.H.A.D.E. Headquarters. Chained, interrogated, and on the verge of being cut from the program, Robyn must defend the one thing she refuses to explain: who she truly is. But when a terrifying new breed of shadow assassins infiltrates the most secure facility on Earth, the agency’s doubts may cost them everything. With whispers of fear spreading through the halls and the fate of S.H.A.D.E. hanging by a thread, Robyn and Vesper find themselves the last line of defense against an enemy born of pure darkness. And before the night is over, the question won’t be whether Robyn belongs in S.H.A.D.E. …it will be whether anyone survives long enough to find out.
