The story revolves around Peter MacBravo, a student living in the Samson Dorms in Icehaven. As he navigates his last week of classes, Peter discovers his roommate Matteo's clandestine activities and becomes entangled in a series of events that will change his life.
In his classes, Peter encounters various characters, including the snide Scott Warner, a science professor with Rivers lineage, and Thaddeus Kiszamazte, a history teacher from Covengard house. The discussions in class, particularly about the printing press and its implications, reveal differing perspectives among students like Plamen Covinggard and Waylan Silveridge.
Peter's academic journey takes him to a Diplomacy in Trading class run by Professor Ofred Onear, where discussions on inherited wealth and its preservation spark thought-provoking debates.
The narrative takes a dark turn during a dinner with friends when Matteo is poisoned. Despite Peter's efforts to find a cure with the help of Sierra Pennington, Matteo succumbs to the poison. Seeking guidance, Peter turns to Ofred, only to discover that his uncle has arrived in Icehaven.
As Peter seeks out his uncle Gregor, he is led by Tobias "fancy lad" Bjornfoot into the secret network Gregor has been building. The revelation opens Peter's eyes to a world of hidden manuscripts and covert knowledge.
The story progresses as Peter embarks on a school trip to Gesdassas, witnesses griffons in flight, and experiences training with River's knights, ultimately being knighted by his half-brother Francis. However, Tobias reveals a shocking truth about Peter's parentage, connecting him to Edward and uncovering a longstanding feud with the Rivers family. This revelation propels Peter into a complex web of family secrets and hidden agendas.
