Possible New Book. Any ideas??

I have a new book that I'm pondering, centered around New York in the time where the Triangle Shirtwaist Factory Co. Fire happened in 1911. This book will be about a woman named Savannah Walker, who with her best friend Beth, immigrants from England, went to the United States to work. Savannah is taking care of her nephew Johnny, whose mother passed away a year and a half before. 

Savannah is going to be the first main character, but the secondary one will be the man she meets and falls in love with, Jacob Collins, a waiter at a restaurant. 

Let me know what you think.
