Jagmarith, Demon champion of the Blood Wars, detests mortal holidays: winter festivals, ridiculous misshapen hearts, flowers, and other traditions are as weak and ridiculous as the humans that celebrate them. Unfortunately, his dislike does little to protect him from the ancient magic that summons him to the human realm. Stolen from Hell, Jagmarith finds himself at the mercy of Ethan, the awkward, adorable human who has accidentally bound Jagmarith to him. To break free from the bond, Jag must endure a series of gruelling human holidays—Christmas, Valentine’s Day, and more—whilst pretending to be Ethan’s nice, entirely human boyfriend. But between the upcoming Halloween party, the fuss over finding perfectly ghoulish decorations, and the odd, troubling feelings he’s developing for Ethan, there’s now another small matter to deal with: impending Armageddon. Jag is not pleased. 

A lighthearted, feel-good narrative with a pinch of darkness, a dose of humour, and plenty of heart, Ethan & Jag Destroy the World is exactly what I’ve come to expect from Maz Maddox, author of one of my favourite series, RELIC. Ethan’s and Jag’s romance is the right balance of sweet, spicy, and emotional, and their story is a romp from start to finish: from Ethan’s accidental summoning of Jagmarith (second son of Bolor’gath, Champion of the Blood Wars, and carrier of his clan’s armour) to a love so powerful that it almost triggers an apocalyptic end to the world. With parts set during both Christmas and Halloween, it would make for perfect cosy reading in either season, and it’s definitely one I’m sure to visit again!
