Query: Yawn!Yawn!

It would be impossible to count the number of books I have read over the years but I could count on one hand how many I have read to the half way mark then couldn't be bothered to finish - this was one of them. It's such an intriguing idea for a novel yet so little was made of it. It seemed to lack energy and just came across as half-soaked.I kept waiting for it to rev up but after reaching the half way mark only to find it still as ineffectual, I lost interest completely. A work colleague finished reading it but I couldn't even work up the curiosity to ask her what had happened in the end, such was my apathy regarding this novel.
