I thought it was completely unnecessary, and straight up ridiculous at points. An epilogue painfully stretched into 500 pages.
The plot is unbearably slow, the dialogue is corny at best, and the resolutions to the mysteries of the first book are so laughably bad that I couldn't believe the same author had written it.
I hate John, I hate his romance with Brawne, I hate his magic dream powers, I hate all the scenes that take place in the Hegemony, I hate the answer of the time tombs, and i hate the ending.
It even managed to make me hate the god damn shrike. A four armed skeletal demon that moves backwards in time. Suffering incarnate. Built of twisted metal thorns and impales people to live an eternity of pain on a giant tree of death (oops, except not really)
That's a feat in its own right
