I am revising my young adult novel, and am struggling with the 1st chapter. It used to have lots of explanation that I needed to cut--so I did. It used to start with telling--no longer. It starts in-scene, the MC gets her "problem" immediately...but I have a flashback. Is a flashback OK for the 1st chapter, or am I just giving an"info dump"? And, if I do include a flashback, is it fine early in the chapter, or should it be at the end? It does relay important information, and is in-scene the whole time. I'm just not sure about it.
