Swimming for Sunlight by Allie Larkin

Katie's life is falling apart.  She's had two miscarriages and now her husband wants a divorce.  Meeting his girlfriend at the lawyer's office doesn't make her feel better.  She's so sure she's a failure.  So she moves back to Florida with her dog, Bark, to live at her grandmother's house.  Nan has always been a source of comfort for her.  She loved her even when her own mother didn't seem to.  But she's changed, tool.

Atria Books sent me an ARC of this book to read for review (thank you).  It will be published April 23rd.

Nan has lost weight, got her hair cut short and looks years younger.  She still offers comfort and love but she's busy now.  She cooks healthy food (Katie doesn't like it, Nan is vegan now) and she exercises.  She's also playing mermaid just like she and her friends did years ago.

Katie's skills are in sewing so she goes to talk to the tailor she used to work for.  He offer her job before she asks, so now she can earn some money on her own.  As she meets her grandmother's friends, she finds they are still the ones she had before.  She knows Nan has a boyfriend (grandfather has been dead for many years), but she doesn't know who it is.

When she finds her ex-husband is married again and the lady is remodeling the house, it upsets her.  She had the house the way she wanted it, now it's being changed and looks awful.  Not only that but his new wife is pregnant.  She couldn't have any with him and he's replaced her with a woman could.

Between feeling like the divorce must be her fault and remembering her father dying while they were swimming together makes her feel like a failure.  It almost takes a miracle for her to understand that bad things in life happen and you have to keep moving forward.  Sometimes it's no one's fault.

The story ends with her coming into her own and developing a new love interest.  Sometimes life is hard.
