When Lucy, age 5, informs her mother that she is an alien, Maya does what any sensible mother would do. She asks what kind. She is unprepared for Lucy's response.
Essentia is the tale of a little girl's unshakable belief and a mother trying do what is best for her child in the face of mounting evidence that perhaps, just maybe, her daughter is telling the truth.
First, the premise is intriguing. 5-year-old Lucy claims she is inhabited ("imbued") by an alien consciousness. Her mother reacts realistically -- she's proud her daughter is so creative.
Second, the execution is adorable. Lucy painstakingly makes her way through a dictionary because she "needs more words" to explain her existence.
Third, the development is believeable. For a book that [maybe, maybe not] involves aliens, this is important.
Unfortunately, Part 1 ends abruptly. I half-seriously wish I'd waited until Part 2 was available before reading Part 1... so now the question is, do I wait for Part 3 to be available before I start on Part 2?
If you haven't read anything else by G.M. Whitley, try Peace Out. It's available for a very reasonable price on Amazon.com.
