Each book in the Gift Legacy is a stand-alone story with enough backstory built in that you can read them independent of one another. However, each story builds on the one before it, so reading them in order is recommended. The main characters carry on through all the books, and each book introduces new characters. At this point, two more books are planned in the series. The Gift: Betrayal is a a retelling of Book 1 The Gift: Awakening, from a different character's perspective. Read Betrayal after Book 1, or at the end of the series.
