The Forever Affair (Pennington #14)

An unexpected reunion.
Once upon a time Catrin was swept off her feet by darkly handsome Dr. Ashe Hope Ellison. She hoped Ashe's love would last forever, but it turned out to be a brief summer affair. This time Catrin has been swept off her feet once more, into Pennington General Hospital and under the care of darkly handsome consultant ... Ashe! Catrin is soon discharged but Ashe seems to want their renewed contact to continue. In time those feelings of intense attraction are rekindled; Catrin has never really stopped loving Ashe, in spite of his betrayal.

But why is he pursuing her now? Could it be he thinks her little brother, Liam is really the legacy of their summer passion?
