One Summer at Deers Leap What is a Step up & a Step down Transformer? Definition. A present day love story which springs from a tragic wartime romance It is the 1990s. Cassie Johns is a young, lovely writer on the threshold of success after a less than silver spooned girlhood. Driving through the glorious countryside to a fancy dress party in the Vale of Boland, she gives a lift to a mysteriously attractive young man wearing the uniform of an RAF pilot: ready for the party Cassie assumes. But in the evening there is no sign of the airman. Cassie hitherto rational, sceptical, a woman of her times becomes obsessed by Jack Hunter, a pilot whose plane crashed in 1944, but whose long ago love for a girl at Deers Leap makes him unable to rest in peace. Cassies love for the dead hero takes her into an unknown war torn past, where old passion burns and becomes entwined with new.
