The Tree and The Vine by Dola de Jong

This courageous early work of lesbian fiction (1951) tells the gripping story of two women torn between desires and taboos in the years leading up to the Nazi occupation of Amsterdam. Erica, a reckless young journalist, pursues passionate but abusive affairs with different women. Bea, a reserved secretary, grows increasingly obsessed with Erica —yet denial and shame keep her from recognizing her attraction. Only Bea’s discovery that Erica is half-Jewish and a member of the Dutch resistance — and thus very much in danger — brings her closer to accepting her own feelings.
