Cassie Shaw lives an organised life: good job, respectable boyfriend, own flat. However, one part of her life is anything but organised, and that's her love for the extraordinary Darling family: her childhood friends Fritz and Ben, and their mother, Phoebe, who took the young Cassie in and transformed her life. But now Phoebe is ill and she asks Cassie for a very special favour. Concerned about what will happen to her beloved boys, she wants Cassie to find them wives. Cassie can't refuse but it's a tall order. Fritz and Ben have grown from delightful children into terrible adults. They're utterly charming and ridiculously sexy, but also totally unemployable and irretrievably useless. Surely no intelligent woman could be persuaded to take one of them on for life?
