The book begins with Silas Heap finding an infant girl, with dark violet eyes, wrapped in a heavy woolen blanket, in the snow as he returns home with herbal medicines for his wife, Sarah. Silas hides her in his cloak and takes her; on the way home, he is told by the ExtraOrdinary Wizard, Marcia, to raise her as his own, without telling anyone where she came from. As he returns home, the Matron Midwife, who is Agnes Meredith, runs out carrying his newborn son, Septimus Heap, in a bundle wrapped head to toe in bandages, pronouncing him dead. Soon after, Silas and Sarah name the baby girl Jenna and treat her as their own child.
Some years later, the ExtraOrdinary Wizard, Marcia Overstrand, returns and reveals Jenna to be the daughter of the assassinated queen, and takes her away for protection. She also tells them that Jenna is not safe anymore because she is discovered by a spy living next door, who is Linda Lane. However, the
assassin, a“Hunter” working for the Dark Wizard, DomDaniel, follows them, and along with several of Jenna’s family members, and a member of the Young Army named "Boy 412", Jenna escapes to their Aunt Zelda's cottage in the Marram Marshes. In the marshes, Boy 412 discovers both a glowing ring and his own magykal powers.
Marcia attempts to return to the castle, but is captured by the guards and is jailed for a month. While she is imprisoned, she nearly dies. Eventually, the Hunter discovered where the group is staying and leaves to assassinate Jenna, but he is thwarted by Aunt Zelda's freezing and forgetting spell. He also leaves for a new life by becoming a buffoon and lowlife circus clown. They capture DomDaniel’s apprentice, who claims to be Septimus, Silas and Sarah Heap’s son, but he escapes and tells DomDaniel of their location.
In the end, Boy 412 is revealed to be Septimus Heap. DomDaniel had ordered the Matron Midwife to take Septimus, who was the seventh son of a seventh son and expected to have great magykal powers, but accidentally ended up with one of the boys from the army nursery and is the Midwife's son (Merrin Meredith), leaving Septimus to grow up in the Young Army as Boy 412.
