A Walk In The Park by Jane Green
— feeling big smile 
A descrepency, but it didn't ruin the story. You, as a reader, have to be willing to look past the little things. Like whether the dog had stitches or not.
Still this was short and sweet!
I definitely am left wanting more, and wanting to know how this relationship develops further between Bill and Olivia.
In such a short time I was able to see what a talented writer Jane Green is. She pulled me right into their chaotic and funny world, and left me pining away!
Gotta go find more from this author right away!
