 Tess Winters is starting over in Chicago after losing everything she had worked for. While she is settling in and beginning her new business venture, she volunteers to watcher her best friend's son while she and her husband go on a much needed tropical vacation. 
 The only problem is that Tess isn't babysitting alone. For two weeks, she will have to co-parent with her nemesis, Nick. Nick and Ethan are best friends, and since Tess and Fiona are besties as well, Tess has to put up with Nick's brand of jerk often. Normally, she can put up with it for a few hours and then pretend he doesn't exist, but 2 weeks is a long time to have to play nice. 
 Playing nice quickly turns to more as Nick and Tess take the time to actually get to know one another rather than instantly picking fights or staying in neutral corners. And once the walls start coming down the chemistry between them is off the charts. From hate to lust to love, these two feel it all. 
 They are careful though to keep their attraction under wraps in front of Max. Watching both of them as they work together to take care of Max adds a sweet aspect to the story, as does Nick's natural tendency to swoop in and solve problems. 
 When it becomes clear that Tess needs help to follow her new dreams, he does what he can to help her out. As it becomes clear that there is more involved in her business venture than initially planned, he continues to try to keep her safe and protected while still helping her meet her goals. 
 Both characters have issues from their pasts that are unresolved. This gives them a common ground but also means they both have triggers. There were times I wished they could connect dots to make things easier for them. There were other times I wanted one or the other to be able to see what was really going on. 
 But overall this was a fun read with a lot going on. I was constantly engaged in the plot, wondering how the details would all add up in the end. The side characters added another level of interest to the story and had me curious about their own stories. 
 I was gifted a copy in exchange for an honest review.
