Every 16-year old thinks they have the weight of the world on their shoulders. For Avery Kimball this was actually true…she just didn’t know it yet. Life for Avery was completely normal, attending school, hanging out with friends, and spending time with her family. Until the day she finds out that she and her four closest friends have a destiny that will take them far away from their comfortable and safe lives on Earth. Avery learns that she and her friends are actually a group of powerful warriors known as the Protectors, who were charged with protecting the planet of Orcatia, but were killed by the evil Emperor. To save their lives, their magical mentor sent them to Earth to be re-born. It is now their duty to return to the planet and life they have no memory of, and once again serve as its Protectors, fighting the very Emperor responsible for their deaths. Along the way, Avery must contend with battling malevolent creatures, her sometimes fragile relationships with her friends and fellow Protectors, her attraction to the mysterious King of Nightfell, and her own doubts and fears about who she truly is and who she can become.

Its been three months since the Protectors defeated the Emperor, and they're still no closer to finding the evil entity the Emperor warned them about. Only intensifying matters is the arrival of the mysterious Five, who somehow seem to share the Protectors powers, and a disturbing woman from Draven's past, who threatens to open a gateway to the Underworld and release a Demon even more dangerous than the Emperor. Meanwhile, as Avery struggles to control her feelings for Draven, Jade and Eryk continue on with their not so secret affair, until Eryk makes a shocking confession that could tear them apart forever.

The gates of the Underworld have opened and Malvenia, the Queen of darkness and Draven's mother, has been unleashed to wreak havoc upon Orcatia. Now the Protectors must take a perilous journey fraught with new monsters, dangerous trial and even a dragon to retrieve the only weapon that can kill Malvenia…the Nexsliv blade. As Draven and Avery stand together against his mother their connection grows stronger, taking their love further than it's ever been before, but will it end with one of them learning the true meaning of sacrifice?
