The Girl With All the Gifts by M.R. Carey

Leech by Hiron Ennes

The book cover for Leech has a dark estate inside a shadow glass bottle. Fuzzy tendrils come out of the bottle to form the title.

When one of these doctors dies in a remote, snow-covered chateau, another arrives to determine the cause of death.

Full of parasites and aliens, Leech is unlike any Gothic horror you’ve experienced. Hiron Ennes’ debut is perfect for anyone into intense body horror, Frankenstein or The Thing.

Mexican Gothic by Silvia Moreno-Garcia

Noemi is a young socialite in 1950s Mexico City, happy to flirt and dance her way through life. Things get serious, however, when she’s summoned to the mountains to check in on her ailing cousin who recently married a reclusive and wealthy Englishman. When she arrives, she’s isolated from her cousin, instead roaming the halls of the manor when she isn’t having intense nightmares. The longer she stays, the more likely it is that Noemi will never leave the house behind.

Mexican Gothic has everything you could want in a gothic novel updated for twenty-first-century readers: a creepy estate with a malicious vibe, complete isolation from society and strange, hallucinatory dreams. It’s a dark, atmospheric read perfect for the Halloween season.
