Lots (not millions, but lots) of people have had their cancer mysteriously disappear, in this here real world. You need to tell us more about that. What’s different about her? And what does the pregnancy have to do with anything?? What’s different about this baby? Did the baby cure the cancer or did whatever cured the cancer make the baby special or is she special and that’s why the cancer’s gone and the baby’s special, and if so why aren’t they after her too? Why does she have to be a teen? Who’s the main character? She “becomes the centerpiece”… not only do you not tell us her goal, you don’t even tell us if she has any idea that she’s special or targeted. IS she the main character? And wouldn’t there be more conflict available if the baby is already born? Currently the baby is wherever she is but if it’s already out, she has to sleep at some point right? I dunno, just seems limp.
