In the third book of the Prism Walker series, Sara and Molly wish they could cross realms from Earth to Exaltia to visit their elven friends, but they know from experience the portal only opens if they're needed for a mission. Imagine their surprise when Thorn and Sael show up in their California neighborhood! Even more surprising is the mysterious crystal the elves use rather than a prism to cross realms, causing the Prism Walkers to expect all kinds of trouble to follow. Trouble is indeed what happens when the crystal accidentally transports the elves and the Prism Walkers not to Exaltia but to Mandriland, a land unlike anything they have ever seen.
