Rating: WARTY!
A Lilo when I was younger, was the brand name of an inflatable raft for floating around in a swimming pool or at the beach - a cheap plastic thing full of air that inevitably disintegrated before summer was over. That's why this author's name seemed so à propos to me since this novel seemed to be of the same construction.
The weak premise is that this girl's mom suddenly decides, apparently out of the blue, that she's a mermaid and bemoans her missing tail, etc. rather than get her the medical attention and meds she needs, daughter and husband sit home with her bewailing their fate and her fate and their inability to fix the problem, like a sorry bunch of professional mourners at a cheap funeral.
I couldn't stand to read any further than the first couple of chapters. If it had seemed like it had some life in it or some humor, or had seemed like it was going somewhere, I might have given it a better chance to impress me, but it just floated there full of nothing, not even sound and fury, trying to look inviting and shiny, but the air was escaping and the water was cold and it really wasn't remotely appealing at all.
