Book 2.5 in the Kristian Clark and the Agency Trap sub-series.
"I'd tell you I love you... But then you'd make me change the baby's diaper.
Kristian Clark can go undercover for months on end, combat multiple enemies at once, and even teleport through dimensions. He should be ready for everything. But having a newborn child... is a little outside his skill set. And the universe isn't ready for little Shannon either. The tentative layers of the universe begins to peel apart and his adopted son gets pulled through a portal in the hospital. Along with an angry wife and reunited best friend, Kristian travels the dimensions to find his son and somehow find a way to save reality without giving up his little girl. Also includes seven other stories. "
