Dark Matter

So here we are dealing with multiverses, the path not taken, the tree and the string etc etc. and the mind expanding rabbit hole you can go down if you start thinking about them, especially after eating cheese. Starts off at 2000mph before slamming to a stop halfway through for the science bit. 2nd half of the book is a tad trippy and I didn't enjoy it as much as the first. Hard to say much more without giving anything away but just imagine a room full of Cookie Monsters and you are not sure which one is yours.

My mind : Bent
My fancy : Suitably tickled
My whelm : Fluctuating
