Yours to Keep by Shannon Stacey

Image linked from Goodreads

In her first two books (Exclusively Yours and Undeniably Yours , Shannon Stacey took some of the regular romance tropes and straightened out many of the problems most authors have when using those tropes. This book presents the well-trod "Fake Fiance" path. Is she again successful? It's an okay book, but not as good as the first two.
Sean Kowalski is just back from the war. And it appears that he's acquired a fiancee in the form of a woman he's never met. Apparently, Emma Shaw was trying to convince her grandmother that she was doing-just-fine-thank-you-very-much and decided a fake fiance was the way to go. Of course, Emma had just been talking to her best friend earlier in the day and Sean's name had come up so she just blurted it out. Since then, she's had pictures photoshopped of the two of them together and expanded on the storyline. Now her grandmother's coming back up to visit and Emma needs a savior. Sean isn't cool with that. But then his family sort of guilts him into it so he goes along. 
Neither is interested in a complete relationship, but the more they fake it, the more they wonder if this thing could really work...
