What Alice forgot

"When Alice gets up after a knock on the head she has a bit of a surprise. As far as she's aware she's twenty-nine, recently married, pregnant with their first and blissfully happy. But she couldn't be more wrong. After landing on her head in gym class she's somehow forgotten all of the last ten years. Suddenly she has three children she can't remember giving birth to. Her besotted husband Nick now seems to hate her. And an unbearable distance has grown between Alice and her sister Elisabeth. How could so much go so wrong in a decade? Why does she not recognise, let alone like, the person she has become? And can she ever again be the woman she used to be?"--Publisher description.
