This Is Us by Helen McGinn

A story about friends, sisters, motherhood and starting again – one day at a time…

Stella fell in love with Simon hard and fast. He was everything she wanted in a husband, and he seemed to feel the same way about her. More than a decade of marriage later, life is sweet. They have three much-wanted children, a successful business, and a comfortable London home. What more could Stella possibly want?
But then, out of the blue, Simon is gone. Vanished. No one knows where he’s gone or why.
Now Stella, with the help of her friends and family, has to pick up the pieces of her and her children’s life, all the while wondering what she missed. Was her husband who he said he was, and can she trust her own memories of their life together?
