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.

Hannah Brooks looks more like a kindergarten teacher than somebody who could kill you with a wine bottle opener. Or a ballpoint pen. Or a dinner napkin. But the truth is, she’s an Executive Protection Agent (aka "bodyguard"), and she just got hired to protect superstar actor Jack Stapleton from his middle-aged, corgi-breeding stalker.

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.

In the hospital and forced to face the possibility that nothing will ever be the same again, Maggie must confront the unthinkable.

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.
