Get Lucky by Katherine Center
This is a fun book. I enjoyed getting to know Sarah Harper as she finds her way after making a dumb mistake and losing her job in New York City. She goes home to Houston to visit her sister Mackie, who is dealing with infertility issues, and ends up offering to be her surrogate! On top of all that, she also runs into Everett, the sweet guy she dumped in high school.
There were a lot of humorous moments between the pregnancy, her old boyfriend, and her new job. Center also does a good job exploring the ups and downs of the sister relationship, and I really liked how things ended up with them.
