Dream Tunnel — Robert Burton Robinson

A girl makes a dangerous trip through time to get to the boy of her dreams and bring him back to her world. Conroe Williamson travels back in time to meet the boy she has fallen in love with while observing him on a device she found in the cellar: a time travel computer. She must marry and assume her mother's throne before her eighteenth birthday or forfeit her destiny as Queen. Initially, she tricks the boy into thinking they are dreaming together rather than traveling through time, fearing that the truth will scare him away. She is unaware that her evil cousin, who is next in line for the throne, is working behind the scenes to spoil her plans for royalty and happiness.
