Sam Elling is taking the social network to the next level: the afterlife. 

Sam Elling works for an internet dating company, but he still can't get a date. So he creates an algorithm to match people with their soul mates. The technology fixes Sam up with Meredith, the love of his life, but it also gets him fired when the company starts losing all their customers to Mr. and Ms. Right.

When Meredith's grandmother Livvie dies suddenly, Sam  reconfigures the algorithm so that Meredith can keep in touch with her. Mining from all her correspondence--email, Facebook, video chat, texts--Sam constructs a computer simulation of Livvie, who responds to email or video chat just as if she were still alive. It's not magic or the supernatural; it's computer science.

Meredith loves her virtual Livvie, so the couple launches a business to help others through their grief. But as the company takes off, it proves more complicated than any of them imagined.  For every person who just wants to say goodbye, there is someone who can't let go. Meanwhile, Sam and Meredith's affection for one another deepens into the kind of love that comes once in a lifetime, a love that neither of them could live without. But what if they suddenly had to?

In the spirit of One Day, this high concept and emotionally hard-hitting novel delivers a charming and bittersweet love story for the 21st century and a heartrending exploration of the nature of love, loss, and life--both real and computer simulated. Maybe nothing was meant to last forever, but then again, sometimes love takes on a life of its own.
