Summary
When toddler Philip tugs on the wrong thread of time, his older brother Marcus is physically de-aged into a child. The spell won't undo easily. Caught between memory and magic, Marcus grows up a second time under the wary, watchful eye of his father.At first, everyone hopes it will be temporary. But days turn into weeks, and Marcus is forced to confront his past, his pride, and his place in a family that’s trying desperately to hold him close while the threads of time tug him further off course.
From Mythbusters-inspired parachute disasters to midnight snack heists gone wrong, Marcus pushes every boundary Matthew sets—earning more than one sore backside and more than one moment of reflection. As the magic holding Marcus in this childlike state refuses to break, the family must navigate tantrums, trust, time spells, and the relentless ache of love that endures through every age.
With Diana’s quiet wisdom, the twins’ accidental magic, and Matthew’s fierce, unrelenting love—this is the story of a son unraveled by time, and the father who holds fast to the thread.

Summary
“Discipline was a problem, too,” Marcus said. “Nobody followed orders, unless Washington himself gave them. And I wasn’t the only young man who’d run away from home seeking adventure.” [...] “Then I met Matthew,” Marcus said simply.
“Because I had nothing left to lose that mattered,” Marcus replied. “And I thought you might be the father that I had been searching for.”
-Time’s ConvertWhile posing as Galen Chauncey among the Moravians, Marcus defies a direct order from Matthew de Clermont—choosing compassion over caution, and nearly paying for it with his life. When Matthew finds him, bloodied but alive, he delivers a lesson meant to be remembered.
It isn’t the first time Marcus has been punished. But this is the first time it feels like someone intends for him to survive it.
Some bonds are never spoken aloud. That doesn’t make them any less real.***warning contains disciplinary spanking of a young adult by his vampire father-figure who later becomes his vampire father. No actual young adults or vampires were harmed in the writing of this fic***
