@SamMadison thank you for writing THH! I can never thank you enough for writing a story so wonderful it transcends almost all life experiences. :)
I think you should write Seth's POV as a summary of what he went through (Sarah, Divorce, Kyla, New York) not necessarily in that order. Just a glimpse of what his life had been would be wonderful. So what I'm saying is you should totally do his POV for the epilogue. This might not answer every question we readers had in mind, but it will give us a peek into Seth's complicated life.
Hoping to hear from you soon! :)
