To Kill the Past — Janet Laurence

Felicity Frear does not know who she is, cannot remember how she came to be lying in a hospital bed, burned and blinded. The news of her closest relatives' death in the car crash that nearly killed her does not bring grief, though she knows it should. Her inheritance of Kingsleigh, an opulent country estate, means nothing to her.
Felicity Frear has lost her past.
Old acquaintances are hostile and she cannot understand why, for she does not recognize them. Even living in a house she's apparently known since childhood does nothing to push back the gray cloud of her amnesia until the phone rings, and a cold, detached voice says, "Now that you're back, I want what's mine."
