Perhaps it was just me but I felt the first half differed from the second in writing style. The first was very descriptive and extensive in regards to character and worldbuilding. The second was very quick paced and almost hyperactive in nature.At times the story seemed a little drawn out.In fact when I think about it that describes the characters of Silas and his uncle to a tee. Silas is very enthusiastic, daring and bouncy and his uncle is a ratchety, demanding and dull man.Silas spends the entire time trying to solve the mystery that surrounds his mother and whilst doing so he tries to save the world. It is a mixture of magic, other worlds and science. I think it is a book that will draw a specific type of reader. The type that likes their fantasy worlds to be filled with fruit for thought and not just filled with simplistic solutions.I received a free copy of this book via NetGalley.
