So I finished Stephen Baxter's Manifold: Space
last night and picked up what I thought was the next book in the trilogy... only to discover that I'd read the second book first.
So now I'm reading Manifold: Time
... which is the one I'd actually tried to read several times in the past and been unable to get into. Hopefully, having read the second book first and enjoyed it, I'll be able to successfully read the first book this time.
