Fyre by Angie Sage book 7 in the Septimus Heap Series.

Now that Septimus, Jenna, and Beetle are fourteen years old, they have assumed larger roles in their Magykal world. Beetle has become the Chief Hermetic Scribe of the Manuscriptorium and Jenna is waiting to be crowned Queen, but Septimus is still battling the remnants of the Dark Domaine, which will remain until the power of the evil Two-Faced Ring is destroyed forever. To accomplish that, the ancient Alchemie Fyre must be relit—a task that sends Septimus to the very origins of Magyk and Physik, testing both his skills, and his loyalties to ExtraOrdinary Wizard, Marcia Overstrand, and Alchemist Marcellus Pye.

In a journey that encapsulates the entire Septimus Heap series, Septimus will continue to discover the truth of who he is and expand upon his Magykal power and skills. Septimus Heap, Book Seven: Fyre weaves together every singular character from the entire series and incorporates many of the Magykal places from each book. Written with Angie Sage’s distinctive humor and heart, Fyre is the grand finale that celebrates the greatest Magyk of all: When the Fyre inside is kindled and when the Time is Right, anything is possible.
