Suddenly, she's playing by a whole new set of rules. When a trip to the local psychic reveals that Tilda may have special powers, she doesn't want to believe it. And then there's the matter of Magnus Berg, a Neanderthal football player who won't leave her alone. What's a girl to do? Is it possible to lose yourself in a portal, but find your true self in the process? The Rainbow Helix is the first novel in the Rainbow Jumpers Trilogy.
