From publisher blurb:
Mystic Portal is no ordinary bike trail.
They say each new jump leads to another world. You and your friends can't wait to try it! Will you ride a camel? Fight bandits? Meet Bog the ogre? Or end up in an underwater city? Whatever you choose, watch out for mad genies, suspicious merchants and one-eyed creatures with orange fur.
In this book, every choice YOU make changes the story.
Adventures are waiting, so jump on your bike and ride the Mystic Portal.
