Mark Zug Book order (chronological)

On the shortest day of the year, as the Castle is lit with candles and everyone prepares to celebrate, Wizard Apprentice Septimus Heap marks his fourteenth birthday. He has reached a new stage in his Apprenticeship: Darke Week. Awe-inspiring, terrifying, unbelievably important, Septimus's future will depend on what happens during this week. He chooses a dangerous mission to restore his good friend Alther from Banishment. But as he embarks on this trial, something Darke and terrible engulfs the Castle. Septimus and his friends are about to face their most perilous challenge yet . . .

Wolf Boy is sent on a Task by Aunt Zelda, while Septimus and the dragon, Spit Fyre, fly off to bring their friends home, but they all wind up on an island whose secrets are as dangerous as its inhabitants

There's trouble at the Castle, and it's all because Merrin Meredith has returned with Darke plans for Septimus. More trouble awaits Septimus and Jenna in the form of Tertius Fume, the ghost of the very first Chief Hermetic Scribe, who is determined to send Septimus on a deadly Queste. But Septimus and Jenna have other plans--they are headed for the mysterious House of Foryx, a place where all Time meets and the place where they fervently hope they will be able to find Nicko and Snorri, who were trapped back in time in physik. But how will Septimus escape the Queste? "Queste," like all the books in the Septimus Heap series, is filled with nonstop action, humor, and fantastical adventure as Septimus continues his journey of Magykal self-discovery.

The seventh son of the seventh son, aptly named Septimus Heap, is stolen the night he is born by a midwife who pronounces him dead. That same night, the baby's father, Silas Heap, comes across a bundle in the snow containing a new born girl with violet eyes. The Heaps take this helpless newborn into their home, name her Jenna, and raise her as their own. But who is this mysterious baby girl, and what really happened to their beloved son Septimus? The first book in this enthralling new series by Angie Sage leads readers on a fantastic journey filled with quirky characters and magykal charms, potions, and spells. Magyk is an original story of lost and rediscovered identities, rich with humor and heart.
