Hidden Star by Nora Roberts

Subtitle: Starts of Mithra --  A woman walks into a private detectives office with no memory, a bag full of cash and an amazing gemstone.  The detective takes on the case and helps her through trying to figure out who she is and what the story is behind her belongings.  Of course he falls in love with her and there is not much left to the imagination, but the build up of the story is done very well and not much was given away throughout.  There are two more books in this series and I am curious as to how Roberts will continue with the energy and creativeness she has started with in this book.
