This is the first book I read by Jeffrey Archer.Since then, I loved his work. 
 This story is a detailed drama where fraternal twins,Nat and Fletcher are separated at birth.Nat grows up with his real parents,while Fletcher with his foster parents. Though both cross paths every time, they never get to know each other. 
 The time when they finally realise they are twins is when one meets with an accident,and requires a rare blood group type A-. Which only matches with the twin. 
 The only part which disturbs me is when Luke,Nat's son,suicides when he knows his mother's history.Otherwise,it was a good read indeed.
