Sooo this is the author here and I'm really sorry to say that the 3rd book of this series will not be coming out anytime soon. The thing is I have just lost interest in Aphmau. MCD has just turned into dust and she never bothers with it anymore. If a new mystreet season comes out then I might do a mystreet one.
Don't worry I'm not going to let Aaron stay dead. I should be able to finish this series someday. Hopefully. Just not now.
Really sry guys, and go read my stranger things books and soon to be supernatural books cause I've sadly moved on...
