Goodbye for Now by Laurie Frankel
Book starts out with Sam and he's designed a dating program and it's a big hit. He likes Meridith but it takes time for them to really see one another.
After her grandmother passes away he sees how sad she is and knows he has a program using AI that can help and it does and it doesn't.
Really strange happen and they open it to others to try out as they are suffering also. Unheard of what happens next... Few characters easy to keep track of what they each are doing.
Love the scenery and places visited in the book, near Seattle as we've been to many of them.
I received this book from a contest I won.
