Whim believes himself to be the least powerful sidhe at Green's Hill: he is as constant as a bumblebee in a hurricane and as faithful as a stray breeze. Whim's prince believes there is more to him than that and on Litha, the night of the summer solstice, sends Whim into the mortal world where he strives to give a piece of himself to others.
It is on Litha that Whim meets Charlie, a young, desperate human who steals a kiss. Whim steals one back and, in turn, craves another taste of this extraordinary man. Their vows to return next Litha and finish what they started launch a thirteen-year tradition of celebration between the mortal and the immortal, between love and patience, that is sustained by Whim's driving, faithful compulsion to love and keep his human close to his heart.
