The last good book I read was the sacred quest and it's a continueaction of the tennis shoes series.
It's basically about a 15 year old boy going back to the time of the nephites in search of his sister's love. On the way there, his step sister to be, follows him on her motocycle and ends up taking him to the cave where the time portal is located.
While they are deep inside the cave, they find an old friend of theirs. While the boy is going to look for water, he heres a scream and goes back to the spot where his friend was and sees that he and his step sister is missing. He discovers he's being chased by an old enemy and comes across a room which he calls the galaxy room. In all the struggle, him and his step sister break through and land in a raging river that takes them to 70A.D, 30 years ahead of what he wants to be. Then it's all about him finding his sisters love and finding this sacred scroll of knowledge to take to this guy that thinks he's the savior in ten days.
