The Book of Silent Keys

The Book of Silent KeysFor readers who have forgotten what they just read. Linguist Elian Voss can remember impossible sentences-Null Strings that erase themselves from the mind. When he investigates the death of his former mentor, he discovers a blue notebook, a missing page, and a door that opens both ways. But the real door is the one you're holding. The Book of Silent Keys is a literary haunting that doesn't end when you close the cover-it begins.
Because you've already said the sentence. You just don't remember doing it.
