Claire has always stood just outside the spotlight steady, loyal, the one who notices more than she says. But when her younger sister Maddie crosses paths with a man from long ago, Claire finds herself witnessing a story she never imagined.

Five years earlier, Maddie walked away from a summer romance carrying a secret she never shared: a daughter named Ellie, and no way to tell the man who'd never know he was a father. Now Noah Carter is back. Older, successful, still marked by the same quiet charm that once broke Maddie's heart and Claire can't ignore how much Ellie mirrors him.

As Maddie struggles to keep her world intact, Claire sees it all unfold the tension, the almost-confessions, the fragile hope pressed into every glance. When Ellie innocently gives Noah the final clue, everything begins to unravel. And maybe, just maybe, come back together.

Told through the eyes of a protective sister, Through the Glass is a secret-baby romance about hidden truths, family ties, and the quiet bravery it takes to stop running.

Can love survive years of silence and still find its way home?
