Growing up, Jane and Marnie shared everything. They knew the other's deepest secrets. They wouldn't have had it any other way. But when Marnie falls in love, things begin to change. Because Jane has a secret: she loathes Marnie's wealthy, priggish husband. So when Marnie asks if she likes him, Jane tells her first lie. After all, even best friends keep some things to themselves. If she had been honest, then perhaps her best friend's husband might still be alive today. For, of course, it's not the last lie. In fact, it's only the beginning.
