Broken Curse: A New Adult Urban Fantasy Harem Adventure (The Horned Mage Book 1) by Liam Lawson

Caleb Marshal was born with a pair of antlers and despite having an abundance of magic, can't use any of it thanks to a curse. Since he's majoring in magical theory at college, this is a bit of a problem. When an opportunity to break his curse presents itself, Caleb jumps at the chance only to find himself plunged into conflict with drug dealers and magically bound to his best friend's younger sister.

Some curses are not meant to be broken....
