I started this series when I was 11 and finally having the conclusion in my hands was an extreme treat. What I found about this book was how it sped up very fast towards the end, while being rather slow at the start. It did have alot to do though; as well as introducing Lord Sunday to us it needed to sort out the Piper, the Will, the wave of Nothing, the Mariner, the Old One, the Archetect, Superior Saturday and whether or not Arthur would remain human. And thank God it didn't go down the ASOUE route; it answered everything and tied off every loose end in a satisfying and brilliant conclusion.
My favourite book in the series is Sir Thursday but this is easily second place, and is quite a relief after the good but a little bit dissapointing Saturday. Arthur's journey as a charactor really shows here and I'm glad he was able to live the normal life he so wanted, while being immortal just to add to it. Ultimately, this was a superb ending to a brilliant series and I'll miss not counting the days untill the next Keys book comes out. It was one hell of a week for Arthur and one hell of a seven years for me. So long House!
