THIS IS THE third book in The Starborn Uprising series. To fully enjoy this story, it would be best to start with the first book, Out Of Darkness, and then read the second book, If It Kills Me.
This series, The Starborn Uprising, is set fifty-seven years after the events of The Starborn Ascension, which features the characters of Waverly and Remi in their fight for survival. This series can be read independently but the two are linked considerably.
