Cassie Hanwell was born for emergencies. As one of the only female firefighters in her Texas firehouse, she's seen her fair share of them, and she's excellent at dealing with other people's tragedies. But when her estranged and ailing mother asks her to uproot her life and move to Boston, it's an emergency of a kind Cassie never anticipated. The tough, old-school Boston firehouse is as different from Cassie's old job as it could possibly be. Hazing, a lack of funding, and poor facilities mean that the firemen aren't exactly thrilled to have a "lady" on the crew.

Sadie Montgomery never saw what was coming . . . Literally! One minute she’s celebrating the biggest achievement of her life—placing as a finalist in the North American Portrait Society competition—the next she’s lying in a hospital bed diagnosed with a “probably temporary” condition known as face blindness. She can see, but every face she looks at is now a jumbled puzzle of disconnected features. Imagine trying to read a book upside down and in another language. This is Sadie’s new reality.

Margaret Jacobsen is just about to step into the bright future she’s worked for so hard and so long: a new dream job, a fiancé she adores, and the promise of a picture-perfect life just around the corner. Then, suddenly, on what should have been one of the happiest days of her life, everything she worked for is taken away in a brief, tumultuous moment. In the hospital and forced to face the possibility that nothing will ever be the same again, Maggie must confront the unthinkable.

Helen Carpenter can’t quite seem to bounce back. Newly divorced at thirty-two, her life has fallen apart beyond her ability to put it together again. So when her annoying younger brother, Duncan, convinces her to sign up for a hardcore wilderness survival course in the backwoods of Wyoming—she hopes it’ll be exactly what she needs.

Lanie Coates' life is spinning out of control.

She's piled everything she owns into a U-Haul and driven with her husband, Peter, and their three little boys from their cozy Texas home to a multiflight walkup in the Northeast. She's left behind family, friends, and a comfortable life, all so her husband can realize his dream of becoming a professional musician. But somewhere in the eye of her personal hurricane, it hits Lanie that she once had dreams too.

Very pregnant and not quite married, Jenny Harris doesn’t mind that she and her live-in fiancé, Dean, accidentally started their family a little earlier than planned. But Dean is acting distant, and the night he runs out for cigarettes and doesn’t come back, he demotes himself from future husband to sperm donor. And the very next day, Jenny goes into labor.

Emma Wheeler desperately longs to be a screenwriter. She’s spent her life studying, obsessing over, and writing romantic comedies—good ones! That win contests! But she’s also been the sole caretaker for her kind-hearted dad, who needs full-time care. Now, when she gets a chance to re-write a script for famous screenwriter Charlie Yates—The Charlie Yates! Her personal writing god!—it’s a break too big to pass up.

An advertisement has been placed (again!) by the wealthy and eccentric Parloni Sisters. The salary is generous and the employers are 90 years old, so how hard could the job be? Well, none have lasted longer than a week. Most boys leave in tears. Ruthie Midona will work in Providence’s front office, and be at the Parlonis' beck and call, forever. That’s sort of her life plan. If Ruthie can run the place in her almost-retired bosses’ absence, with no hijinks/hiccups, she has a shot at becoming the new manager.

Celebrity cooking show host Marni McGuire has seen it all. She’s been married—twice—and widowed and divorced. Now in her mid-fifties, she’s single. Happily so. She just needs to convince her pregnant daughter, Bella, of this fact. And maybe convince herself, too. Especially after Marni’s efforts to humor her determined daughter result in a series of disastrous dates that somehow prompt Marni to wonder if maybe the right man for her is still out there after all.

If Darcy Barrett hadn’t met her dream man when she was eight years old, the rest of the male population wouldn’t be such a let-down. No one measures up to Tom Valeska, aka the best man on Earth, not in looks, brain, or heart. Even worse is the knowledge that her twin brother Jamie saw him first, and claimed him forever as his best friend. Tom’s off limits and loyal to her brother, 99 percent. One percent of Tom has had to be enough for Darcy, and her adoration has been sustained by his shy kindness. And if she’s honest, his tight t-shirts.
