The title says it all really. I'm used to books going over my head and that doesn't usually detract from my enjoyment but I have to say that the final reveal in this one just did not make sense to me. Maybe I drifted off at a critical point but why did the aliens need actual hatches to communicate, it isn't like they used them themselves? And where did the power for the first hatch come from. I know the hatches were powered by the enegy released by the end of time but did this mean that they had to wait for the end of time to build the first hatch? Surely they would have been dead then? Also it seems like the author had too many characters and didn't know what to do with them once they had served their purpose
Not my favourite Baxter. Pity.
