The SonMultichapter fic - not finished yet
FIC HEALTH WARNING: You can think of this as an AU if this major character death revealed at the beginning would bother you but if you really do not like major canon characters being killed off I'd avoid reading this for your own sake. I want fic readers to be happy. :D
This is set a few years after Heartlines and Vorpaths and linked to that epilogue where we discover Ivan has a son he doesn't know about.
