My book opens during my protagonist's commute. Without getting too much into it, the commute is a major theme of the book and ties into the plot. The actual plot involves the antagonist (love interest). The commute is an important setting in the book ad there qill be many scenes depicting occurrences during the commute that reveal the protagonist's outlook and ways that she handles situations.
My problem is that while I am sure the hook in the beginning is interesting (an event which occurs during the commute), I am at a loss at how to now go and begin introducing the antagonist. He does not commute with her (until the end of the book). So on the first few pages of the book, she's commuting to9 work. The event happens, and then what? I don't want to introduce the people at work because they are not as important as the antagonist. The people at work are important but not until later.
I was thinking about switching it so that she is going home instead of going to work, but it feels more intense to talk about the rush hour commute in the morning. It might be easier to have her get off the train, go wherever, and meet with the antagonist. But I first imagined it to start on monday morning, and I am not sure if changing that will be the right thing to do.
Any ideas or advice would be very much appreciated.
