Ever since she can remember, Aly has been fixing everything around her: her parents' marriage, her colleagues' work problems, and her friends' love lives are just a few examples. After a chance meeting with an ex who has gone from living in his parents' basement to being a married project manager in three years, she realizes she's been fixing her boyfriends, too....

So, Aly decides to put her talents to good use and, alongside two work friends, sets up the Fixer Upper, an exclusive, underground service for women who are tired of unpaid emotional labor. Using little tricks and tips, Aly and her friends get the men to do the work themselves--to get out of the job they hate, sign up for that growth seminar, do more parenting.

As Aly tackles her biggest "fixer upper" yet, she'll have to come to terms with their complicated history and figure out how much to change someone she'd always thought was perfect as he is....
