Jayben and the golden torch by Thomas Leeds

Can one boy with no memories save the world? In the Earth world, a boy dreams of faraway lands to escape life with his horrible aunt. In the Elf world, he wakes up with a mysterious golden torch but without any clue who he is – except for the compass he pulls from his pocket, engraved with one name: JAYBEN. Jayben discovers that many moons ago, a giant put a dark spell on the golden torch, and the elves forgot everything that had come before. Now they hang precious memories in jars on trees, just to try to remember. But a new darkness grows among them. An evil villain called Null is burning down the forests, hellbent on finding the torch and becoming the most powerful being ever to live. If Jayben can find his own magic and ignite the torch with its fierce violet flame, his power will be unstoppable.
