They escape their troubles by immersing themselves in their fantasy world, where they reign as king and queen. As their bond deepens, they face challenges both in Terabithia and in the real world. When tragedy strikes, Jess must find a way to cope with his grief and honor Leslie's memory. Through the power of friendship and imagination, Jess learns valuable lessons about love, loss, and the importance of cherishing the moments we have with those we care about.
