Sorcery and Small Magics (The Wildersongs Trilogy, #1)

Leovander Loveage is a master of small magics. He can summon butterflies with a song or turn someone's hair pink by snapping his fingers. Such minor charms don't earn him much admiration from other sorcerers (or his father), but anything more elaborate always blows up in his face. Which is why Leo vowed years ago to never again write powerful magic. That is, until a mix-up involving a forbidden spell binds Leo to obey the commands of his longtime nemesis, Sebastian Grimm. Grimm is Leo's complete opposite, respected, exceptionally talented, and an absolutely insufferable curmudgeon. The only thing they agree on is that getting caught using forbidden magic would mean the end of their careers. They need a counterspell, and fast. Chasing rumours of a powerful sorcerer with a knack for undoing curses, Leo and Grimm enter the Unquiet Wood, a forest infested with murderous monsters and dangerous outlaws. To dissolve the curse, they'll have to uncover the true depths of Leo's magic, set aside their long-standing rivalry, and much to their horror, work together. Even as an odd spark of attraction flares between them.
