Firstly and as usual, I received this book free for the purposes of an honest review. Also as usual I'll give my candid thoughts below.
On the positive side, Varley's novella is well written, contains only a few typos (which is increasingly rare in eBooks) and reasonably entertaining. Her grasp of character is strong and I could imagine the three young ladies in this book really existing somewhere in a not-too-absurd universe. Also, the book isn't just about entertainment it does have a bit of a deeper point. In the interest of avoiding spoilers I won't say what that point is but you'll find it if you read the book.
To the negative, the story is surprisingly simple and I feel like I just read a YA (young adult) novel. It's possible, of course, that it is targeted for a YA audience but it's not labeled as such so I have to assume that it's for adults. As such it loses a star because it's just so very, very simple.
In summary, this one is well written but a bit hollow for anyone over the age of 18. The themes are rather childish and lacking in complexity but on the whole a well-written story. This simplicity will be a positive for some and a negative for others. I leave it to the reader to make that determination for themselves.
