The Entanglement of Rival Wizards by Sara Raasch

Ali Hazelwood meets Dungeons & Dragons in this enemies-to-lovers fantasy academia romcom where rival grad student wizards are forced to work together without killing—or falling for—each other.

Will they conjure love, or evoke chaos? Two rival wizards are about to find out.

Sebastian Walsh: Evocation Department. Human. The first of his family to pick college over the military.
Elethior Tourael: Conjuration Department. Half-elf. Pretentious asshole. The latest legacy Tourael at Lesiara U.
Both: Mageus Research Grant finalists.
Sebastian refuses to let anyone snatch this away, least of all a snob riding on old money. But what’s worse than a nemesis stealing your grant? You could both get it. Under the condition you work together.

Sebastian is in hell. Thio’s broody. Takes up their shared lab space with his projects . . . and biceps. Brings treats for Sebastian’s familiar . . .
. . . and is nothing like Sebastian thought.
When Sebastian’s past with the Touraels forces him to choose his research or Thio, the decision should be simple. But while working with his rival is volatile . . . falling for his rival might blow up Sebastian’s future.
