Alana S Portero’s debut novel "Bad Habit" ("La mala costumbre") is a vivid exploration of the struggles faced by trans people, set in 1980s Madrid. It follows the protagonist, a trans woman, through her journey towards self-acceptance amidst a backdrop of drugs, violence, and complex relationships. The book, described as a "juxtaposition of the sacred and the profane," incorporates mythical parallels and showcases characters who are deeply affected by their harsh environments.

The narrative begins with the protagonist's childhood encounter with death, shaping her future perceptions and relationships. As she grows older, she finds herself in the company of wise but world-weary trans sex workers, seeking self-worth and mentorship. These relationships are a central theme, highlighting the protagonist's gradual acceptance of her community’s outcasts.

Portero’s historical knowledge enriches the narrative, providing depth to the characters and their struggles. "Bad Habit" has garnered critical acclaim and has been endorsed by notable figures like director Pedro Almodóvar. The novel’s poignant portrayal of the protagonist’s internal and external battles is supported by its striking and lyrical prose.

The book has experienced significant success in Spain, becoming a bestseller and winning multiple awards since its release last year. Its translation by Mara Faye Lethem captures the intensity of the original, although some phrases may not translate seamlessly.

"Bad Habit" stands out for its emotive language and evocative descriptions, reflecting the protagonist’s complex journey and the harsh realities faced by trans individuals during that era.
