Kill To Love (Hearts & Heathens #1) by Penny Sunday

Book #1 in the Hearts & Heathens Series

Tropes: Dystopian Dark Rom-Com, Fated Mates, Enemies to Lovers

Good girl Delphine has waited all her life to find her Soulmate, only to find out that he is a... notorious serial killer.

Delphine De Astor has never cried. She doesn't feel much of anything and has hidden her lack of emotion all her life for fear of being outed as Soulless – evil and unlovable.

Unfortunately, Delphine has also never felt her heart search for her Soulmate. Deemed Soulless, she is thrown into an Execution Battle where she must fight to the death against other Soulless for ten days (with advertisement breaks for stain remover). Pant-less, and armed with only sunscreen, Delphine runs into cannibals, psychopaths who are probably just Gemini’s, incestuous lovers, a madman in a pink sequined crop top and…Dig Graves.

Dig is a notorious, dark haired serial killer who hides his eyes behind heart shaped sunglasses. Long ago he had tried to kidnap Delphine and tenaciously hunts her down in the Battle.

And when they meet? Delphine’s heart finally beats.
