Love is the last thing on Jack Harrington’s mind when he sets out to meet Andi Walsh’s flight. Recently back to work after spending more than a year tending to his comatose wife, Jack is focused on getting through each day and caring for his three daughters. However, the moment he sets eyes on Andrea Walsh, the interior designer who has come to decorate the hotel his company is building in Newport, Rhode Island, Jack begins to wonder if Andi might be his second chance. After a disastrous marriage, Andi, single mom to a hearing-impaired son, isn’t exactly looking for love, either, but that’s what she finds with Jack. The two embark on a long-distance relationship fraught with challenges as they balance the needs of their children and dueling careers while Jack continues to care for his wife, Clare. Just when Jack thinks his life is once again settled, he is confronted with a new challenge that tests him in ways he never could've imagined, leaving him to wonder if "happily ever after" is in the cards for him.

Marking Time continues the story begun in Treading Water as Clare Harrington begins a new life. She’s considered a miracle, but everything that’s happened since she recovered from a three-year coma has been something less than miraculous. Now left to grapple with the aftermath of a selfless decision, she is home from the hospital and trying to figure out what the next chapter in her miraculous recovery has in store for her. Meanwhile, her eighteen-year-old daughter Kate, a talented singer and songwriter, sets out to pursue her musical dreams in Nashville. Her parents have agreed to allow Kate to spend a year there, but they couldn't have anticipated Kate falling in love with a much older man. Her newly divorced parents are forced back together to confront their wayward daughter. Spanning from Newport, Rhode Island, to Nashville, Tennessee, to Stowe, Vermont, Marking Time is the story of new beginnings and new loves.

In a drunken stupor, Brandon O'Malley frightens his brother Aidan's girlfriend, enraging his brother and the rest of his family. Aidan offers Brandon the choice of rehab or jail, and Brandon reluctantly enters treatment. While in rehab, he confronts the lifetime of secrets and resentments that fueled his spiral into alcoholism, and these revelations have a major effect on his entire family. When he returns home expecting to resume his supervisory role in the family’s construction business, Brandon learns his father has retired and put his younger brothe, Colin, in charge. Brandon is unhappy to be given the job of renovating an apartment building where he loses his heart to an adorable five-year-old tenant named “Mike.” After he falls hard for Michaela, Brandon becomes involved with her mother Daphne, who is running from a past that will later test his sobriety and his mettle as a man.

The story left unfinished at the end of Marking Time picks up ten years later when Kate Harrington goes after the man she left behind when she set out to chase her dream of music superstardom. Now she has everything she ever wanted, except for the one thing she can't live without. What will Reid say when she shows up unannounced in St. Kitts, looking to reclaim their lost love? And what will Jack, Kate's father, have to say when he hears she's gone back to her first love, a man Jack once considered a friend? And what do you think will happen when Jill Harrington, Kate's sister, attorney and manager, faces off with Ashton Matthews, Reid's son, the same man who made life miserable for Kate many years ago? The sparks will fly when the Harrington, Matthews and O'Malley families gather in Nashville for a Christmas none of them will ever forget!

The long-awaited finale to Marie’s beloved Treading Water Series is HERE at last! Maggie Harrington is in way, way over her head, running Matthews House, the shelter her famous sister Kate and brother-in-law Reid have opened, using Reid’s family estate to provide support to women and children in crisis. This job is just what Maggie needed after a disastrous episode in New York—or so she thought. The constant life-or-death challenges she encounters have her emotions on a rollercoaster of soaring highs and crushing lows. Living near her sisters Kate and Jill and regular rides on Kate’s beloved horse, Thunder, are the best parts of her new life. When Maggie hires Brayden Thomas to run an equine therapy program for the resident children, she does so knowing he’s hiding something from his past. But his sterling professional reputation and qualifications have her taking a chance on the handsome horse whisperer, who quickly becomes a friend and confidant. It doesn’t hurt that he’s also smoking hot, funny, easy to talk to and damned good at his job. It’s her first time being “the boss.” Surely she ought to maintain some semblance of professionalism when it comes to Brayden, right? But day by day, hour by hour, he makes himself essential to her and has her teetering on the fine line between personal and professional as her feelings for him intensify. The Harrington girls are together again in Nashville! Come along for a visit that’ll include the arrival of Kate’s baby, Jill’s wedding to Ashton and Eric Harrington’s high school graduation. Jack, Andi, Clare, Aidan, Jamie, Frannie and the O’Malley family also appear in the Treading Water Series finale!
