Though I am not much studied on the views of Angelology, nor do I have figurines or birdbaths of angels or send out daily memes of them. Forma Lux is a fictional angel set in the format of scripture as I understand it. The Bible speaks about some who have entertained angels unaware, and how do we know we have not been visited? They have appeared to declare God's warnings or foretell what is coming. Forma Lux (form of light) is a harbinger sent from the kingdom of heaven who gives anticipatory sight of what is to come and is a nonmortal servant of God. She is the "hark," the "fear not" messenger to people in individual settings throughout this book. She is a bit snide in a humorous way but can give a piercing dialogue to people who need to hear it. The reader may find the dialogue, the characters, and the unique situations written with passion in a different style or interesting way.
The book has three different stories. First story ("Forma Lux and Old Soldiers Fade Away") is about an elderly gentleman unaware that he is at the last days of his life. He fought in WWII and was facing his grief of killing men so long ago and has bitterness against God. He is visited by Forma Lux, and I won't tell you what happens next.
The second story ("Forma Lux and the Space Cloud") is the beginning before Forma is assigned to earth by God. She is in a solitude place where her duties are to catch souls that had problems, even after their death, accepting their salvation after their conversion. She dialogues with Ephriam Jones, who fought in the English Marston Moor Civil War in the 1600s. You might enjoy his out-of-body flight, leaving his soul and meeting up with Form Lux and the dialogue the two have.
The third story ("Forma Lux: Heaven's Harbinger"), Forma Lux is assigned to Plymouth (Plimoth), Massachusetts, to the pilgrim plantation. They find her living in the woods in a mysterious house by herself, and they call her to task. Of course, there is a witch trial but most of the characters are historically believable at the time. Some of the happenings, or at least the accusation of the happenings, are said in court documents of my own family during that time--that dang floating hammer in the chimney, invisible roof stumpers... Wait for the end. It is a good one.
