Sorcery and Small Magics (The Wildersongs, 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. Though such minor charms don't earn him much respect, anything more elaborate always blows up in his face, and so Leo vowed long ago never to use powerful magic again.

That is, until a mishap with a forbidden spell binds Leo to obey the commands of his longtime rival, Sebastian Grimm. Grimm is Leo's complete opposite--respected, exceptionally talented, and absolutely insufferable. The only thing they can agree on is that revealing the curse between them would mean the end of their respective magical careers. They need a counterspell, and fast.

Chasing rumors 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 alike. To break the curse, they will 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.
