Blood Matters - Family by Choice, #4

It's been five years. Five years since GenEx. Five years since the world was completely changed. And now Alex feels responsible for integrating extrahumans with the "normals." He must also take care of the gravely-ill Mister Lupino. When his son, Nicholas, suddenly reappears in his life under tragic circumstances, Alex doesn't know if he can take it. Maybe that's why he starts seeing people that aren't there, and hearing sobs in the night.
Maybe it's all of the stress. Or, maybe, it's something else.
