The Granddaughter - Paperback

Madeline Lagrange, granddaughter of the chairman of the "Lietzensee Dance Club" considers ballroom dancing merely a necessary cultural skill that she learns without ambition. Then she meets the club's square dancers. And she loses her heart - to the dance and to the group's caller, the American Chris Rinehart.
Chris is captivated by Madeline from the very first moment. But he's the coach of the group and she's underage. So he's fighting his growing affection for her and denies her his feelings.
While Madeline tries to seduce Chris with the uncompromising determination of her seventeen years, her grandfather is willing to do anything to expel him from the club to break them apart.

Each book in the series can be read as a stand-alone.
