While BookTok is best known for its YA and romance recommendations, "Mexican Gothic" (£7) by Silvia Moreno-Garcia opens up another side of the community: horror fans. After receiving a frantic letter from her newlywed cousin, debutante Noemí goes to investigate and potentially rescue her cousin from a dangerous situation. When she arrives at their isolated house, she's immediately wary of her cousin's husband, his mysterious family, and even the house itself, which seems to have something supernatural hanging in the air. It will take all of Noemí's strength to discover the truth and save her cousin — and herself — from the secrets hidden there.
