Stirring the Embers (Starting Over #1)
Mary Jo Putney

Kate and Donovan married too young and stayed too long in a dangerously destructive marriage. Ten years later, surely they're mature enough to co-exist peacefully. But the embers of attraction swiftly flare into flame again.
Now, they must confront the pain of the past if they are to have a chance for a future and save their business from a saboteur they're beginning to suspect of murder.
Originally published in 2000 under the title The Burning Point, this is the first in a series of three contemporary romances by acclaimed and bestselling historical romance author Mary Jo Putney.
