The Keeper or Jenna Wiseheart, a young girl with a unique heritage, was about to discover if she has a spirit animal bond, a rare link between both human and beast that gives great powers to both. Jenna had saw a flash of light and then her spirit animal emerged.
A wolf. Jenna had summoned a beast of legend. Now her fate is set. The new heroine and her spirit animal must band together on dangerous quests. A dark force from the past is rising, but only she and the Four Heroes have the power to stop it.
But Jenna Wiseheart and Devin Trunswick had both crossed paths once, but as friends. But the second time, they had crossed again as enemies. But when Devin returned as a mysteriously cloaked boy named Worthy, could she really trusts him? After they all had been through together?

Disclaimer: Don't worry, I'm writing for fun. Though, the Keeper and the Four Heroes are going to be around teen ages, like fourteen or fifteen.
