It was around mid October 2011, shortly before Halloween when Ms. Weiner posted on facebook about her crazy GPS and wondered if she could turn it into a story. Several days later she posted "Jonesing for a new book? I wrote a spooky short story about a possessed GPS. Fingers crossed you'll be able to buy it on Amazon on 10/31. Happy Halloween!" That short story is Recalculating. It follows a women whose abusive husband passes away. While cleaning she finds a gps which turns out to be possessed.
It amazes me that Ms. Weiner was able to write a story so quickly. This book was great, but like most short stories it leaves you wanting more.
