   Summary

   Following his father's untimely death and his step-mother falls into a coma, Roboute Guilliman is sent to a residential group home. Stuck in a too small attic bedroom with Sanguinius and the Lion, the trio must contend with the burgeoning feelings between themselves and the thing stalking the halls at night.
