I read this one for the WWE Women in Genre challenge and now rather wish I hadn't. Grimspace reminds me a lot of the now ubiquitous urban fantasy/paranormal romance one finds on bookstore shelves these days, but in a sci-fi setting. The book is chock-full of the cliches in that genre. The writing is quite weak, pacing is off, and there are plot holes all over the place that are big enough to fly spaceship through.
I give this book two starts because there are flashes of good writing and I know there are people who would enjoy this book. I just wasn't one of them.
