I've always written my novels in limited 3rd POV, but I am anxious to try something new. That and the majority of Urban fantasy seems to be written in 1st person, so I decided to go with the flow. Anyway, the story I want to tell has two main characters. Is it acceptable to switch from one 1st person POV to another as long as I do it at chapter breaks? Like chapter one would be told from the 1st person POV of main character A, while chapter two would be told from the 1st person POV of main character B. Are there other novels out there that have employed a similar style?
