Character from The Locked Tomb by Tamsyn Muir
The Fourth House's teenage necromancer — a kid who was too young for Canaan House and died proving it.
Isaac is a genuinely talented necromancer trapped in a situation designed for adults. He and his cavalier Jeannemary were the youngest pair at Canaan House, informally adopted by Magnus and Abigail, and treated by most other postulants as children playing at a game they couldn't win. He resented this but also, on some level, knew they were right. He was murdered at Canaan House. He was fourteen.
Young, small, and desperately trying to look older than his fourteen years. Dark hair, earnest face, and the build of a teenager who hasn't finished growing. Wears Fourth House colors and carries himself with the determined seriousness of someone who knows he's being underestimated.
