Hahaha, another romance novel. This time the theme was about time travel, interesting! Well, the story runs like this, a pilot (spaceship driver) named Caleb from 23rd century was stranded in the 20th century after his spaceship had an accident. Caleb was saved by Libby and they fall madly in love with each other. Then, although Caleb have a chance to go back to future, he gave up the chance to be with Libby and sent the spaceship back to 23rd century (autopilot) to tell his parents that he's OK.
Then, Caleb's brother, Jacob (a very brilliant scientist apparently) managed to recreate a time travel spaceship and went to 20th century to bring back his brother. Before he have a chance to meet his brohter, Jacob met Libby's sister, Sunny first and they fall in love. However, Jacob didn't want his parents to be sad for losing another son. So, he decided to go back to his time. Well, Sunny sneaked into the spaceship to follow him to the future. So, two happy endings.
