Excellent, vivid worldbuilding with plenty of details to draw the reader in, a diverse cast and a likeable, relatable main character.
The book is in dire need of a good editor, though - there are superfluous and missing commas aplenty, some misplaced quotation marks, typos and formatting errors, as well as some grammar errors and plain clumsy writing (especially in the beginning of the book). 
There is also a problematic moment towards the end of the book, when a minor character, a Shaman from the Amazon, is introduced and presented as "speaking" in broken English. This doesn't make sense, given that all other characters communicate perfectly fluently through telepathy. I doubt that this was intentional on the part of the author, but it still others the native character, making him seem as less-than. Just goes to show how far we all have to go to unlearn our internalised racism. 
However, none of this detracts significantly from the reading experience. I really enjoyed spending time in Jenny and Tidbit's world, and am thankful both that the author realised her lifelong dream of becoming a writer, and that she chose to make the first book in the series free through Prolific Works.
