The Archer and his Rosebud by Mindy Michele

At nineteen, Willa Hawthorne had ambitions, a determination in her heart, and plans for the future. All of which vanished the moment she saw two pink lines.
College parties and independence are replaced with late-night feedings and howling cries. As a single mom in a town that isn’t her home, she’s hanging by a thread. When her newborn’s rare moment of sleep is interrupted by her noisy neighbor, the thread snaps.
Rebuilding his life after his marriage left him in shambles, Archer Thomas isn’t expecting his new neighbor to have a breakdown at his front door. The last thing he needs is to become involved, but Archer can’t help stepping in when the struggling young woman’s daughter steals his heart.
Willa isn’t one to ask for help, but when life flips the script, sometimes accepting the hand of the gorgeous single dad next door is the only answer.
