Please help me find a book

okay I read this fairly recently but for some reason the name is slipping me. Its basically about this witch that moves to Ireland(could be Scotland) and summons an incubus to help her with magic, hes trapped to her and trying to find a way to be free, and she feels bad that she traps him so she too is searching ways to help him. its a slower romance but its really good, i just cant find the title. MFC is a curly redhead, sorta ditsy. MMC is broody with long hair and tan skin. im shitty at descriptions lol but if that helps pleaaase!! i think its on KU and its also a newer book!
