You don't have to decide yet. See if the "right moment" pops up. Are you going to share anything about your story with them? That has an added layer as your MC has cancer. (It is a subplot but a very important one.) Try not to worry about this yet. One thing at a time. Only two more after this! Woohoo! (Don't forget to mention the hot flashes to your doc. These are normal. Everyone gets these with taxol but the severity differs. Just touch base with her. How hormone sensitive is your cancer? I don't remember.)
