Another winner by Shannon Dittemore!

Brielle has a gift that most people don't even realize is possible: she can see the celestial. After learning about spiritual warfare and angels in Angel Eyes, Brielle is now trying to learn how to balance carrying life as before and sharing what she has learned with those she loves. Just as she thinks she has things under control, everything begins to fall apart. She can hear Celestial worship, her father is relapsing back toward not wanting to deal with grief, Jake is keeping something important from her, and she finds out secrets surrounding her mother's final days.
I loved this book! The first one was a wonderful, fresh perspective on Spiritual warfare, and this one follows that same path. I will warn you that it ends in a terrible place, since it's the second in a trilogy, but that is a small price to pay for such a wonderful series.;)
