Rating: 5/5 stars
Title: Saphirblau (Sapphire Blue)
Author : Kerstin Gier
Precious Stone Trilogy
Sapphire Blue is the second installment of the Precious Stone Trilogy and it was a really good addition to the series. All of the characters develop in this book so well. Although, I must admit, if Gideon was a little bit less immature I would not mind it at all. The episodes of time travelling in this book are plenty, and through these episodes we manage to understand a lot about this secret society and this hidden word. Generally, it was a really quick and easy read!
