Tenth anniversary edition • With a new Introduction by the author

In the near future, disease will be a condition of the past. Most genetic defects will be removed at birth; the remaining during infancy. Lou Arrendale, a high-functioning autistic adult, is a member of the lost generation, born at the wrong time to reap the rewards of medical science. He lives a low-key, independent life. But then he is offered a chance to try a brand-new experimental “cure” for his condition. With this treatment Lou would think and act and be just like everyone else. But if he was suddenly free of autism, would he still be himself? Would he still love the same classical music—with its complications and resolutions? Would he still see the same colors and patterns in the world—shades and hues that others cannot see? Most important, would he still love Marjory, a woman who may never be able to reciprocate his feelings? Now Lou must decide if he should submit to a surgery that might completely change the way he views the world . . . and the very essence of who he is.

Thoughtful, provocative, poignant, unforgettable, The Speed of Dark is a gripping journey into the mind of an autistic person as he struggles with profound questions of humanity and matters of the heart.
