Killer Unicorn Apocalypse

After a coven of murderous unicorns destroy a young woman's ancestral home in an attempt to seize a legendary magical artifact, she's forced to embark on a quest to bring it to safety - no matter what the cost. But to do so, she'll have to forge an unlikely partnership with a shapeshifting unicorn who was sent to kill her.
Together, the pair must survive encounters with a team of eccentric knights, a platoon of genocidal elves, a dream-hijacking bounty hunter, a clan of cannibal gnomes and a terrifying alpha unicorn who is trying to annihilate the entire human race. They'll also have to overcome something much more dangerous: their taboo, irresistible attraction for each other.
