The young stu­dent of Scot­tish his­to­ry, Caitri­ona “Cat” Camp­bell, has to do research for an essay on Samhain, the night of Octo­ber 31st to Novem­ber 1st. Her final des­ti­na­tion is the Val­ley of Tears in the High­lands, as the roman­tic town of Glen­coe (Gael­ic: Gleann Comhann), scene of a 17th cen­tu­ry clan mas­sacre, is also called. She no longer believes in great love, let alone the myths of the past. But the spir­it of Dusten Mac­Don­ald teach­es her some­thing dif­fer­ent. Dusten is impris­oned in the faerie realm and cursed. Only to Samhain he is allowed to show him­self to mor­tals in search of redemp­tion. She decides to help him. How­ev­er, she does not end up in the fairy realm, as orig­i­nal­ly planned, but in the 17th cen­tu­ry. There she meets Dusten. But how can she pre­vent the inevitable from hap­pen­ing?
