Remember Me by Roxanne Tully

Elizabeth Owen has just exposed her terrible secret… in a houseful during a family reunion. Desperate for forgiveness from her loving husband, but too terrified to ask for it, she decides to escape for a day.
On her way back home, Elizabeth suffers a terrible car accident. Her husband Matt rushes to her side, the past 48 hours now an insignificant blur. When his wife finally opens her eyes, she doesn’t remember him. She doesn’t remember her sinful secret. She doesn’t remember anything.
Now, Matt Owen is forced to battle between the anger he needs to constantly suppress and the anguish over losing the woman he loves. And he knows that the only way to get past the bleak reality he’s been handed is for Elizabeth to get her memories back.
So when the doctor gives him specific instructions on helping her remember, why does Matt find himself doing the exact opposite?
