The Blue Door, the first book in The Threshold Series, introduces Prissie Pomeroy, a teen who discovers she can see what others cannot: angels all around. Even more startling is the surprising secret she uncovers about people she thought she knew. As she wrestles with this unexpected ability she must come to grips with the spiritual battles surrounding her. Especially when she learns she received this gift because God has a unique role for her in his bigger plan. But if she's to fulfill it, she'll need faith like never before.
This exciting debut by author Christa Kinde draws on the rapidly growing interest in angel stories, an emerging trend in teen and preteen supernatural novels. Boys and girls alike will appreciate her gifted storytelling that captures their imagination with things beyond human sight. And parents will appreciate the family-friendly tone and godly messages maintained throughout this intriguing tale of adventure and spiritual warfare.

From Booklist
Fourteen-year-old Prissie Pomeroy leads an ordinary existence, chatting with her somewhat shallow friends, making plans to attend the county fair, and enjoying time with her family. Everything changes, however, when she realizes she can see angels--as in, celestial beings walking the planet. Suddenly, the young farm girl's life is turned upside down as she discovers she is a key player in a spiritual battle being waged on earth. Her Observer, Koji, is startled when he realizes Prissie can see him as a young human teen, although he remains invisible to other earthly eyes. Prissie begins to lean on him for advice and support, even though at times she feels she doesn't need it. Kinde's world building is strongest in her angel characters, each of whom has a distinct personality, much like the humans they watch. Less praiseworthy is that none of her angels are female, which might have provided more interest to girl readers. The language and plot of this first title in a series are well geared toward middle-graders, and the positive Christian message may please some parents. Grades 6-8. --Julie Trevelyan
