Query: Touching story of what Plato, Kant, and many others have argued about

This was an excellent read about what is real and what is not. A little mental illness is mixed in to make this a wonderful read. I want to believe Hilton...I do believe Hilton...Do I? Should I? This books makes you gasp, tilts you forward, tempts you to peek at pages ahead, and was an excellent fictional thriller on subjects/ideals that really exist and keeps many philosophers at an eternal state of tug of war. I loved this book. Tananarive Due deserves a genre of her own. Absolutely love her.
