I really don't know how it's possible that this series keeps on surprising you. I thought that I've seen everything, that I know everything but with each next book I read, I'm being proved wrong. The truth is: you can't predict what will happen next, no one can. And maybe that's what keeps you wanting to read this book and making the reading so thrilling?
I think that this book is special amongst the whole series. My heart was racing like wild while I was reading it. Thirst, there was this giant wave that came from door of Kalipso's bookstore and which flooded Kilmore Cove. Then it turned out that good old doctor Bowen is bonkers and he wants to destroy all Doors to Time. And Thirdly, there is this awful plan to burn Villa Argo. Mostly because of those three things reading this book was like a roller-coaster ride. The anxiety, sadness, frustration - this was too much and sometimes I just wanted to cry.
The plot mainly takes place in Kilmore Cove, which is a nice change from the constant travel through non existing lands. There is a part where Jason takes off to an snowy land in search of answers for the most important questions, but it's rather small comparing to Kilmore Cove part.
Though I love this series, there is one thing that annoys me: teenage love. Maybe I'm too old and it looks so stupid to me, almost laughable. I just can't remain serious while teenage love appears. For this, I'm sorry. But love between Ulysses and Penelope... this is something different, something beautiful that moves me to tears. And although there's scarcely anything written about them, comparing to the vast amount of information on other things, you can feel that it's something special.
All in all: an amazing read. And as always, can't wait to read the next book.
