Goodbye For Now by Laurie Frankel

Sam Elling is a romantic genius who invents a program that matches up soulmates. Using it, Sam finds true happiness with co-worker Meredith. When her grandmother, Livvie, dies, Sam's at it again, creating another program to simulate Livvie — but how far will Sam and Meredith take this death-defying act of love? Their own relationship is what could end up on the line.
