Sorcery and Small Magics

Leo is good at small, pretty magic and nothing else, until a forbidden spell goes wrong and binds him to obey his longtime rival, the gifted and insufferable Sebastian Grimm. Neither can afford to be found out, so they head into the Unquiet Wood, full of monsters and outlaws, after a sorcerer who can undo curses. Rivals stuck together, a very slow burn that only starts here, no spice, open ending.
