This is book four in the Septimus Heap series. Here you can read about book three.
In book three, Nicko (Septimus’ brother) and Snorri went back in time 500 years to try to find Septimus, who had actually managed to get back to the future already. Now Nicko and Snorri are still trapped back in time in the house of Foryx.
In this book, Septimus, his sister Jenna, and Beetle all go to the crossroads of the forest to begin a journey to help bring heir friends back. They are intercepted by Tertius Fume (first ever Chief Hermetic Scribe) and the evil Merrin Meradith, who want to darken Septimus’ fate by sending him on the Queste, which nobody has ever returned from.
I loved this book! It was exciting, interesting, and a great story.
