The Asylum Prophecies — Daniel Keyes

Raven began the day in an asylum, a disturbed young woman with multiple personalities recovering from another suicide attempt. But now she holds a secret that could save thousands of innocent lives. Buried deep in her splintered subconscious are details of an impending terrorist attack against the United States -- details that her kidnappers cannot let her reveal. As Raven summons all her strength to fight her captors, an American agent races across the globe to rescue her and find the key that will unlock her trapped memories before it's too late.
