I picked this up as holiday reading once the other books I'd taken for the ride had been read. And to be honest, this is just what this book is: holiday reading. It's a page turner in two parts that run side by side. Firstly, the part set in the real world, and secondly, the part set in the imaginery world (which only our protagonist can see). The real world is interesting, the imaginery world confusing (and in parts, just plain boring). There's gradually a convergence, but on the whole not a very interesting one. Could do better. But it filled a gap and wasn't bad. Not a great recommendation, I know.
