First, I have to state right up front that I may be biased, as Jemima Pett is a writing pal and a friend. I also read two or three drafts of the book and offered feedback, so of course I think it's great!
But seriously, when I proofed the final copy, even knowing the story quite well (that was the 3rd reading) I couldn't stop reading. The story just grabs me, and I'm definitely in love with the characters! So, you can discount my bias and still know you should read it if you like some good science fiction with just a touch of fantasy, some grin-inducing situations, and a few things that Asimov never put in his books.
The first of a series, the story comes to a satisfying conclusion but does prepare us for the next book--which I'm eagerly awaiting!
4 stars: I really liked it.
