Molly Carpenter goes through some changes in the last several (as of Mar 2017) Dresden Files novels. Specifically:
In Changes,
she becomes traumatized by helping Harry to arrange his own death
Then, in Ghost Story ,
she is living on the streets and makes even her family members nervous. I suppose it helps that Harry finds out about the memory wipe and she can work out the guilt over helping him arrange his death...
But, at the start of Cold Days,
She has an apartment which she earned for helping the svartalves and she seems closer to herself.
Has Mr. Butcher written a story which details what Molly did between Ghost Story and Cold Days to improve herself to get that apartment?
