My favorite book by Sidney Sheldon, the story involves you in a way it's almost impossible to stop reading until the last page. You find yourself rooting for Tracy from the beginning and cheering her on with every heist and laughing at the police attempts to catch her and Jeff(and also rooting for their romance).
Also, Danial Cooper will give you chills with his psycho-stalking-like behavior towards Tracy. If you like Sidney Sheldon, this is a MUST READ.
