Changeling's Crown by Juli D. Revezzo
When Ianthe began her career as a faery godmother, she stumbled so badly that Snow White will probably never speak to her again. After a long suspension, she's finally been given a chance to redeem herself...but everything on this latest assignment is going wrong. But why? Worse, she definitely doesn't need an attractive mortal man distracting her from her duties. Of course, needs and wants are two different things. Briak has had his eye on Ianthe for a very, very long time, but he's been waiting for just the right moment to make his move. Despite the fact all hell's about to break loose on his watch, he can't resist the opportunity to insert himself into her earthly assignment. Can he convince Ianthe of her true calling and thereby win her heart? Or will his subterfuge ultimately cost him her love?
