Not quite four stars, but at the same time 3 would be a little harsh. 
 If you read this then I'd advise you to completely disregard the first chapter. That's right, don't even bother reading it. It has pretty much zilch to do with the book and lowers the WHOLE tone - it's childish and unnecessary and I wish I hadn't read it. 
 At times this book feels childish, too childish even for it's young protagonist. It is fantastical almost to a fault. Perhaps it's too boyish for me... If anything it's a boy-book. 
 But the start of this book seemed to promise tea, and I love tea. Some of my favourite quotes in this book were the tea ones, lamenting the growing price of tea and wondering how the subjects of Great Britain would ever get by with the dwindling imports. 
 This book is action packed and full of twists and turns and even a few surprises and mystery. And the ending leaves it open for more, which I would read despite my annoyances and some parts. 
 Thank you to NetGalley for a review copy.
