Written by a man with Asperger's Syndrome, The Journal of Best Practices: A Memoir of Marriage, Asperger Syndrome, and One Man's Quest to Be a Better Husband by David Finch, is the only "autism book" that has ever made me deeply empathize with someone who has aspergers.
The author clearly has strong autistic traits . . . and he writes of his very deep love and appreciation for his wife. Ummmm . . . wow? Uncommon, almost unrealistic, and yet, oh, so encouraging!
Full of extremely foul language and definitely rated R for adult content (so much so that I may not keep it around for fear of my children picking it up and reading it), I heartily recommend that all aspie's wives read this book.
Here's a post that introduces the book, written by the book's author: http://jerobison.blogspot.com/2011/12/love-is-blind-marriage-is-eye-opener.html
