Ava Monroe has a gift , a gift which renders her the power to open the Garden of Eden or the Gates of Hell.
For years, she has been haunted by the same dreams of people and places unknown to her. She doesn’t realize the dreams are a result of the power that resides in her blood until she is attacked by a group of fallen angels who want her to open the gates of hell. Thankfully, the guardians of heaven come to Ava’s rescue. They have a simple assignment -- or so it seems -- to protect the Key to Eden and convince her to open the Garden of Eden. Instead, they're faced with defending an emotional teenager who refuses to give up her life to fight with the guardians until after graduation.
When the fallen angels arrive, a fight ensues and one of heaven's guardians becomes the first casualty in the one of the final battles of war between heaven and hell. With Ava’s help, the guardians will stop at nothing to unlock the Garden of Eden and grant heaven's wish for paradise on earth and the ultimate destruction of hell.
