Children of Shadows - The Indigo Chronicles, #3

Single mother Ella is struggling. About to turn forty, the last thing Ella needs in her life is more complications, but she suspects her brush with angels may not be over yet. Ella's daughter, Indie, is keeping a huge secret. But it's not until she meets the new kids at school that she begins to learn about her true powers. Luci has been busy. With the help of her whisperers, she's figured out how to destroy the Angelic Realm.
The only problem is the one person who can help her secure the final ingredient won't help. As Indie explores her growing abilities, she enters a world of fate and power that Ella left behind sixteen years ago. She will soon discover that this world is on the brink of war, and that she may be the most powerful weapon of all. For over two thousand years, Ella's and Zac's lives have been intertwined.
When fate no longer exists and the past catches up to the present, will the bond of blood be enough to unite two worlds?
