This is obviously a very vague synopsis but the book centers around five girls who are all friends and deal with different struggles etc. However, the book places them in three different time zones (eg: modern day, 80s and 60s) to show how they dealt with their issues at different points in time. So for example, one character gets an abortion in modern day but doesn't in the 60s because it was shamed. It also heavily centres around mother and daughter relationships. Any ideas would be appreciated!
