[Megan]

I'm going through a break up with my boyfriend and one of my close friends and was wondering if there are any books similar to this plot?.

heroine breaks up with her boyfriend then starts losing her friends. she thought her life was over until she meets the hero .

I don't know any characters or that , am just looking for books with a plot like that one.

the books genre can be from YA romances to contemporary romances.
